Message

Convener International Advisory Committee

It is a great pleasure and honour to welcome you all to the international conference, „Updates on

Natural Products in Medicine and Health Care Systems„, sponsored by the INSPIRE programme

from the British Council, to be held in Khulna, Bangladesh. This conference builds on the

successes of national seminars and workshops on mangrove plants from the Sundarbans, held in

Khulna University, during the past couple of years.

The main objective of this day-long international conference is to evaluate and update the

knowledge on the contributions of natural products, plants and plant-products from the

Sundarbans for example, to medicine and healthcare.

With participation of renowned as well young natural products scientists from India, UK, and all

parts of Bangladesh, I am sure that this conference will provide a unique platform to exchange

views on advances in research in natural products especially in relation to promoting plant-based

medicines and primary healthcare.

The conference will also highlight the current demands and market situation of plant-based

medicinal products in Bangladesh, and offer some pointers as to how to improve the quality of

such products. It is expected that several new approaches, e.g., nano-science, chemometrics,

principal component analysis, modern extraction technologies, and bioassay developments, will

be at the heart of several oral and poster presentations.

I wish all participants a stimulating, thought-provoking and an enjoyable conference.

International Conference Organizing Committee

In recent years, the medical value and industrial stimulus have provided by the availability of a

number of plant-based drugs, isolated from plant materials of oriental folk-medicine. It is likely

that there remains the possibility of discovering novel compounds with significant and valuable

pharmacological properties to be isolated from plant materials, and that, incidentally, clues to

some of them may still be found in the folk-medicine of indigenous people. In particular, the rich

and comparatively uninvestigated abundant flora of South Asia especially Bangladesh require

careful and systematic investigation, and it is gratifying to see that collaborative efforts are

underway among the institutions of South-South and North-South cooperation. This international

conference is an outome of research partnership between Khulna University, Bangladesh and

University of Wolverhampton, United Kingdom.

We hope that everyone will find everyone's contribution not only in the respective session of

their preferences but also the other sessions would fulfill everyone's expectation. However, with

respect to the initially foreseen sessions, we have been obliged to introduce several changes, that

reflect the number of contributions submitted in the various subfields of natural product

chemistry, and thus your present scientific interests. We hope the conference will contribute to

maintain active scientific discussions through exchange of ideas, theories, methodologies,

expertises and the recommendations during the sessions and aside.

The conference could not be organized without the financial support of International Strategic

Partnerships in Research and Education (INSPIRE) project, British Council. We would like to

thank British Council for the contribution towards success of the conference.

We are also indebted to the International Conference Organizing Committee, student volunteers,

other committees and the chairs of the sessions as well as to members of CSS Ava Center,

Khulna especially Md. Mottasim Billah, for their respective and really appreciated contributions.

We wish all the participants an excellent conference and a pleasant stay in Khulna.

Traditional medicine for an affordable and positive global health.

Professor A B M Faroque*

Former Dean, Faculty of Pharmacy, University of Dhaka, Dhaka-1000, Bangladesh &

President, Bangladesh Pharmaceutical Society

Abstract

There is a tremendous development in last 100 years in the health care sector. Many new drugs

have been discovered and some of them have brought almost a revolution in treating human

ailments. Thus sufferings of the ailing people have lessened, longevity has increased and overall

health indices have improved. But accessibility and affordability of the poor to medicine is still a

major issue to be solved globally. There is no single solution or magic bullet towards these

questions because these issues are not only complicated, but also complex. Against this backdrop

place and utility of Traditional Medicine (TM) has emerged as a complementary vehicle towards

affordable healthcare to many un-served or underserved poor population across the world,

especially in the developing and least developed countries. According to WHO (2004), the

average per capita spending on pharmaceuticals in the developed countries is nearly $400, but

that in developing countries is only about $4. Even when someone gets infected with HIV/AIS, a

patient in the developed country spends an average of $300 per annum, while a similar patient in

the developing country can spend only $5. These examples indicate that it is now high time to

integrate TM to modern medicine which will deliver a holistic synergy leading to an affordable,

available, effective and safe healthcare for all citizens of the world. But TM has deficiencies too,

majors of which are (i) lack of validation, (ii) lack of standardization, (iii) lack of integration into

the health care infrastructures, (iv) lack of appropriate policies, (v) lack of regulatory control

over the misuse and abuse etc. Earlier it was widely believed that TMs are very economic to use

and that is the main reason behind TM‟s popularity amongst the poor. But current trends that

have been set by some of the traditional medical men and TM manufacturers, reflects that in

many a cases TMs are (i) much costly than the modern medicine counterparts, (ii) much misused

and abused due to illegitimate practices by both the prescribers and the manufacturers, and (iii)

even in many cases modern active pharmaceutical ingredients are being added to „popular‟ TMs

without any declaration in the label. These bottlenecks must be removed must be removed for the

sake of integration of TMs into more meaningful and positively responsible horizons of national

and global health in future days.

Abstract

Rapidly expanding population and practice of unsupervised prolonged steroidal contraceptive

usage are the leading cause of a number of life threatening disease conditions. The present study

has been carried out to evaluate the ethno-contraceptive use of roots of Piper betle (PBR),

followed by toxicity studies. The hydro-ethanolic extract of PBR loaded in 2-hydroxypropyl-

beta-cyclodextrin (BCD) was administered in female rats from day 1 to 7 of pregnancy. PBR-

BCD (1:1, w/w) formulation exhibited optimum contraceptive potency at the dose level of 250

mg/kg p.o. It showed impeded estrogenic and progestational activities and prolonged the length

of estrus cycle, altered release of gonadal hormones and gonadotropins. Detailed

pharmacological analyses followed by chronic toxicity studies were performed to predict the

reversible nature of the developed phytopharmaceutical. Pharmacometabonomics analyses by 1H

NMR revealed the favorable serum lipid profiling of the developed formulation over the

ethnomedicinal preparation. The histological and biochemical estimations detected the reversible

contraceptive potential. Bioactivity guided fractionation was carried out for identification of

active constituents present in PBR. Piperolactam A (PL) is isolated from the ethyl acetate

fraction of PBR. PL-BCD complex showed 100% anti-implantation activity at 5 mg/kg/day for

first three days of pregnancy (n=10). PL might be useful as a promising lead compound of next

generation female contraceptive.

Systemic evolution of traditional medicine

M. Aftab Uddin, Ph.D

Professor and Chairman, Department of Genetic Engineering and Biotechnology, University of

Dhaka

Abstract

Natural products are organic compounds that are formed by living systems, which have some

biological effect within the cell or organism that is responsible for their production or on other

organisms. In the history of medication, it is the natural products that were the only healing

substances for health and healthcare, in nutrition, and prevention of diseases. The first use of

medicinal plants for healthcare or to cure illness or diseases is not exactly known to anybody.

But it is sure that the search of some remedy for some discomfort is a patrimony and observation

of self-medicative behavior in animals, where sick animal utilize certain plants that they usually

ignore, over past decades that attributed to whole human race about medicinal plants and which

we shall know and preserve. In reality, animal behaviorists, ecologists, pharmacologists,

anthropologists, geochemists, and parasitologists have all contributed to this truly multi-faceted

discipline. From different literature it is quite clear that the discovery of medicinal plants were

mainly based on serendipity. Most times the discoveries were simply results of the search of new

types of food to maintain good state of health by trial and error. In searching food Man found the

poisons, the allergens, and other produced somewhat different effects such as they increase the

sweat, they defecate with greater extent, eliminate joint pain, and other discomfort effect, cure

for fevers and headaches etc., etc. The first written text on the use of medicinal plants is about

4000 years old Sumenian clay tablet that records remedies of many illnesses. Herbalism is

thought to have started some 60,000 years back. By 400 years B.C., Hippocrates, the father of

medicine, who tackled medicinal plants in a more scientific manner than ever before? The long

and the oldest history of Indian medicinal system are well established with written records going

back around 3000 years, known as Ayurveda, has left written reference from 800 A.C., where

they describe 800 species. Currently more than 6,000 plant species are known and used in Indian

Systems of Medicine (Ayurveda, Siddah, Unani and Homeopathy in addition to modern

Medicine). Natural products of plants, terrestrial and marine animals, and microorganism derived

preparations were being used by these systems. It is the purpose of this paper to provide the most

recent information an updates on natural products in medicine and healthcare system.

Keywords: Natural products; Ayurveda; Unani; Homeopathy.



Plant Drug Nanomedicines for Pharmacokinetic Development and Commercialization

Professor Arup Mukherjee*, Ph.D

Head, Division of Pharmaceutical & Fine Chemicals Technology, Department of Chemical

Technology, University of Calcutta, 92 A.P.C.Road, Kolkata- 700009, India.

Abstract

The progress in human history is intricately linked to the scientific utilization of natural

resources. Human health is one area in which, substantive knowledge in plant drugs remained

enormously rewarding through the ages. Modern molecular interpretation for plant medicines

however could only be established in 1806, when, Friedrich Sertürner a pharmacist, isolated the

bioactive principle morphine, from Papaver somniferum. A long list of purified plant drug

molecules was since developed. Some of the more recent examples in that line include, Taxol,

against cancer from Taxus brevifolia and Artemisinin against multi-drug resistant

falciparum malaria from Artemisia annua. In most cases though, the bioactivities for known

chemical entities of plant origin are well established but, their therapeutic applications are

marred due to chemical incompatibilities and pharmacokinetic limitations. Taxol for example is

water insoluble and need a solubilizer cremophor EL, which in itself causes severe adverse

reactions. Artemisinin, in addition has a very low biological half life. Nanomedicine is a

converging discipline with unbound potentials in the health care sector. Robust scientific studies

have already established that particles in nanosize can modulate biological distribution in vivo or

be targeted based on surface chemistry. We have used a variety of techniques to develop

different plant bioactive nanomedicines. Andrographolide for example was nanoparticulated in

cationic modified Poly (d,l-lactic-co-glycolic acid), PLGA for applications in cancer

chemotherapy. Quercetin conjugated in gold nanoparticle was devised as a chemotherapeutic in

drug resistant visceral leishmaniasis. Silymarin flavonolignans drug delivery devices were

developed to mitigate irreversible paracetamol hepatotoxicity. Mysticism around nomedicines is

now only historic and several pharmaceuticals including those from plant bioactives are in

market place. „Abraxane‟ a cremophore free albumin based taxol nanoparticles is one successful

anticancer agent in market. Polyethylene glycol conjugated artemisinin nanosystems were also

developed for enhanced solubility and sustained release. It is likely that a slow down in drug

discovery that is seen in recent past can only be rejuvenated from the low cost nanomedicine

developments from different natural known chemical entities.

Keywords: Taxol; Artemisin; Nanomedicine; Bioactive compound.

Medicinal plants in combating the emerging threats of Type 2 Diabetes

Begum Rokeya*, Ph.D

Professor & Chief Research Officer, Department of Pharmacology, BIRDEM, 122 Kazi Nazrul

Islam Avenue, Dhaka-1000, Bangladesh.

Abstract

Diabetes mellitus is now a major public health problem in the developed as well as developing

countries. The International Diabetes Federation predicts that the number of people living with

diabetes will rise from 366 million in 2011 to 552 million by 2030. The burden of Type 2

diabetes is enormous due to increasing prevalence, chronic course, disabling complications and

high treatment cost. Diabetes management studies show that conventional antidiabetic agents

like sulfonylureas are the least durable agents followed by metformin and thiazolidinediones.

Therefore, search for improved antidiabetic drug has been continued. Over the last several years

the incretin-based therapies have got significant importance although they are very much

expensive. Therefore, search for improved drug(s) against diabetes has remained a major goal

among the biomedical researchers. Since approach of the scientists for synthesis of these drugs

has not yet brought expected results, many of them in recent years, are focusing their attention on

natural compounds to find, at least a lead, for antidiabetic agents. It is well known that

Bangladesh and neighboring countries have a rich tradition in indigenous herbal medicine. A

number of medicinal plants and their formulations are being used for the treatment of diabetes in

the traditional system as well as in ethnomedicinal practices which needs to be scientifically

evaluated. Following a standardized approach collaborative studies between BIRDEM and

Chemistry Department of Dhaka University are being conducted on plant materials for more

than two decades. So far 84 plants from Bangladesh and neighboring countries have been

screened for antidiabetic properties. Screening results showed that majority of these plants have

got significant blood glucose lowering effect, although they differed in the nature of the animal

models and prandial states. Some of the active extracts were tested for long-term glucose and

lipid lowering effects. A number of sub-fractions and compounds isolated from the active

extracts were tested on pancreatic islets and beta cells for insulin releasing effects. Inhibition of

carbohydrate absorption through gastrointestinal tract in rats by inhibiting disaccharidase

activities, effects on GI motility and inhibition of platelet aggregation indicated the presence of

various principle(s) in hypoglycemic plant extracts. Based on the obtained results controlled

clinical trials have been performed with a couple of plants.

Abstract

Advancement in modern science and technology has enhanced the quality of human life. At the

same time, very fast life pattern with stressful condition all through the day has created a lot

enormous stress in modern life, has resulted in the incidence of variety of psychiatric disorders

like anxiety. These are recurrently accompanied by somatic symptoms such as tachycardia,

dizziness, palpitations, sweating, nausea, irritability, insomnia, and impaired concentration.

Severe side effects and addiction liabilities associated with long term administration of widely

prescribed synthetic drugs have aroused the attention of researchers towards natural resources.

Dregea volubilis (Family: Asclepiadaceae) is extensively used for insomnia as traditional

medicine in different parts of India. Anti-anxiety activity study was done with methanol extract

of Dregea volubilis leaves (MEDV) using light-dark model and elevated plus maze model as

experimental protocol. Four groups of Wistar rat containing six animals in each group were

taken for the study in each model. MEDV at two dose levels (200 and 300 mg/kg body weight)

as test drug and diazepam at dose 4 mg/kg body weight as standard drug were administered

orally. Vehicle was given to the control group. MEDV in both doses significantly enhanced the

time spent in light chamber in a dose dependent fashion (p<0.001) in light-dark model as well as

it enhanced the number of entries and time spent in the open arms significantly (p<0.001) in

elevated plus maze model which were comparable with the standard. It can be concluded that the

leaves extract possess significant anti-anxiety activity and the study will help for utilization of

MEDV in different herbal preparation.

Abstract

In the era of antibiotic resistance, natural products notably plants, microbes and marine

organisms continue to be an important source of lead compounds for drug discovery. Indigenous

medicinal plants from different countries are under-exploited for antibacterial drug discovery

whilst more than 80% of the population in Asia and Africa depend on medicinal plants for the

primary health care. The overall aim of the plenary lecture is to provide a brief update of my own

research in natural products chemistry. The methods used in the bioassay directed isolation and

identification of lead compounds involved extraction, initial fractionation and further purification

followed by identification. Each of the plants was Soxhlet extracted sequentially with hexane,

chloroform and methanol. Based on activity, the extracts were further fractionated by VLC

followed by purification by a range of chromatographic techniques including gel filtration,

column chromatography, preparative TLC and HPLC. The compounds were identified by

spectroscopic techniques including MS and NMR (both 1D and 2D). The antimicrobial activity

was determined by microdilution titre assay. Extensive phytochemical investigation on the above

plants led to the isolation and identification of a wide range of compounds- terpenes, steroids,

lignan, simple phenolics, flavonoids and isoflavonoids including some new compounds. Among

the compounds, a new isoflavone, 4',5,7-trihydroxy-8-(1,1-dimethylprop-2-enyl)-isoflavone

showed highest activity against Staphylococcus aureus. Its MIC was found to be 1.57 g/ml

(0.005 mol). In conclusion, the isolation of potent antimicrobial agents has reasonably justified

the medicinal uses and inspires scientists for further research.

Keywords: Antibiotic resistance; Lead compound; Medicinal plant; Phytochemical

Globalization of traditional medicine (TM) – Safety, efficacy, therapeutic and clinical

evidences

Pulok K Mukherjee, M. Pharm, PhD, FRSC

Director, School of Natural Product Studies, Dept. of Pharmaceutical Technology, Jadavpur

University, Kolkata-700032, India.

Abstract

Globalization of traditional medicine (TM) is necessary for health care with assessment of its

safety, efficacy, therapeutic and clinical evidences. New technology and science has developed

many techniques and systems to raise the traditional medicine compounds for global existence.

Establishment of global and/or regional regulatory harmonization is necessary for its

development and promotion through scientific validation. Traditional medicines are

mostly indigenous to a country or region. It has developed through daily experiences and mutual

relationships between people and nature. For thousands of years they have cured diseases and

prevented illness, thereby maintaining health. The huge secondary metabolite resources of

medicinal plants- their phyto-constituents are widely respected for their unique chemical and

biological features, and are gaining global acceptance because they offer natural ways to treat

diseases and promote healthcare. The global health survey in 1970, boost up the use of ancient

systems of medicine for better healthcare. Scientists around the world are searching for

medicinal plants as alternative medicine and their potential in health care. The development of

natural products requires the confluence of modern techniques and integrated approaches related

to their research in various fields of science through International coordination and cooperation.

When adopted outside of its traditional culture, traditional medicine is often called

complementary and alternative medicine. It is a fact that inappropriate use of traditional

medicines or practices can have negative or dangerous effects and emphasis is being given on its

scientific validity to ascertain the efficacy and safety of the practices and medicinal plants used

in this system. To combat with the growing market demand, there is urgency to expeditiously

utilize and scientifically validate more medicinally useful plants globally – which needs

globalizing local knowledge and localizing global technologies in this area through international

collaboration and co-operation.

Abstract

„Sweet Sultan‟ (Centaurea moschata L.) belongs to the genus Centaurea (family: Asteraceae alt.

Compositae), which comprises ca. 600 species of herbaceous thistles and thistle-like flowering

plants. Most of the Centaurea species are native to the Old World, but also cultivated elsewhere.

Centaurea moschata and many other species of this genus are wellknown for their medicinal

properties, and folklore uses for the treatment of several ailments including cancer, diabetes,

diarrhoea, hypertension, malaria, rheumatism and tumour. A variety of secondary metabolites,

belonging to the classes of alkaloids, flavonoids, lignans, sesquiterpenes and simple phenolics,

with potential anticancer activities, particularly against colon cancer cell-lines, have been

reported from different Centaurea species. The presentation will present an overview of our

work on C. moschata and related species of this genus to date, with particular emphasis on

compounds with potential anti-colon cancer activity.

Keywords: Centaurea; Centaurea moschata; Asteraceae; CaCo-2; colorectal cancer.

Abstract

Bangladesh has a long tradition of indigenous herbal medicinal systems based on the rich local

plant diversity which is considered as a very important component of the primary health care

system. And more than 75% of its population is getting their primary health care through

Ayurved, Unani, Homeopath, Herbal and other traditional medicine systems. A good number of

such traditional manufacturers are using about 550 medicinal plants from various sources. And

only 10 percent of these are available in Bangladesh and rest 90 percent is being imported from

broad. A medicinal plants cultivation in the rural area of northern part of Bangladesh at Monga

affected areas especially in the small strips of land in the homestead or village road side of

marginal or low income people which made them economically self sufficiency creating impacts

in environment and increasing social values and integrity.

Scope of drug discovery and the role of Stress in the Formation of Lead Molecules in Medicinal

Plants

Abstract

Natural products have been long regarded as mainstay of drug discovery programmes. India from its

rich valuable source of traditional system “Ayurveda” offers an array of drug discovery leads to be

useful for the treatment of several ailments. Diabetes has spread its toxic tentacles all through and

every sections of the society. Recent failures in the discovery process of new chemical entities have

made natural product researchers to look into history of herbal drug use for search of leads. Reverse

pharmacology approach forms the major weapon of search of anti-diabetic leads. Long

documented/undocumented use of different unexplored medicinal plants by the ethnic groups forms

the first step in the search of anti-diabetic lead. Expectation of low toxicity for humans from plants

used traditionally can be easily accepted as these plants have been thoroughly tested owing to their

use since ages. With the increasing hectic lifestyle which has made the pathogenesis of diabetes so

complex. Modern medicine attempts to use a single compound to hit single target of a particular

pathway for combating the related disease which may not prove to be a long-lasting management

strategy. On the other hand, traditional medicines exert synergistic effects due to its galaxy of

phytoconstituents hitting multiple targets and thus acting through multi-mechanistic pathway.

Henceforth, drug discovery spectrum from traditional medicine has now two basic objectives a)

Discovery of new chemical entities from plants mentioned in literature of traditional systems of

medicine and b) Development of standardized polyherbal formulations based on traditional

medicines formulae. However, to gain global acceptance and better therapeutic management for such

metabolic disorders it is essential that such drug discovery approaches be integrated with modern

biology to evolve a holistic system biology approach for the management of diabetes. Through this

integration, drug discovery from Ayurveda can make a strong impact on the western world.

Traditional medicine has a long history of serving mankind all over the world. Phytochemicals

obtained from traditional medicinal plants are presenting an exhilarating panorama for the expansion

of modern therapies to combat against knotty diverse ailments. Amongst most precious medicines

from phytosources are analgesic agents like morphine and codeine from Papaver sominiferum,

antimalarial agents like quinine and antiarrythmic agent like quinidine from the bark of Cinchona

species, antitumor agents namely vincristine, vinblastine from Catharanthus roseus, taxol from taxus

species, hepatoprotective agents mainly silymarin from Silybum marianum and antidiabetic agent

like gymnemic acid from Gymnema sylvestre still playing important role in orthodox medicine. As

the interest in medicinal plants mainly resides on its secondary metabolites as health aid the research

on secondary metabolite biogenesis, isolation, preclinical and clinical studies has been accelerated in

recent years. The local environment sets the agenda of plant growth and yields in a given habitat and

regulates the performance of individuals. Production of active ingredients in medicinal plants also

gets influenced by the environment factors. Samples from various agroclimatic conditions collected

at different stages of plant growth and covering the various plant parts needs to be investigated for

obtaining the best out of a medicinal plants.

Traditional Medicine in Newer Drug Delivery Systems

Abstract

The most primitive ground of treatment is governed by the use and/or practice of traditional

medicine, which is actually of different preparations or formulations from the plant, animal and/or

mineral origin available through our surroundings. Even in the present world the use of

phytomedicines is quite popular and thereby widespread in the most of the population around the

world. This is an integral part of the healthcare system in the developing and underdeveloped

countries of the world. Interestingly, many developed countries are also inclining to the use of

different traditional medicines alongside with their most popular synthetic/allopathic treatment

regime. Though traditional medicines ensures patient‟s compliance due to their different attributes

like natural origin, less toxicity, more availability, ease of preparation, no regulatory barriers, etc.,

they often cause harm to health for their improper and unregulated use. In many occasions we find

the aqueous extract of different plants and/or plant parts like roots, leaves, barks, etc., are more

beneficial for the different ailment purposes. For the application of traditional medicine we mostly

prefer either oral or topical route. The polar constituents extracted from the natural origin are often

larger in molecular size and thus show retarded transport into the targeted organ due to lipid-bilayer

conformation of biological membrane. On the other hand, the non polar constituents of the plant

origin show decreased solubility in the aqueous body fluid and thereby also cause limited

bioavailability on oral ingestion resulting in poorer efficacy. For these reasons, sometimes we use

larger doses of plant extracts or actives for availing the desired effect, which in turn cause toxic

and/or lethal effects in some cases. Hence, it is very much necessary to develop some newer drug

delivery techniques through which the drug could be delivered more precisely and unaffectedly to the

target tissue for producing better effect avoiding the unwanted effects at maximum level. Liposome,

phytosome, ethnosome, nanoparticles, implants, transferosomes, microemulsions, proniosomes, etc.

are some newer drug delivery systems that have been found very much promising for delivering

different kinds of plant extracts quite successfully by oral/topical route to overcome their poor

bioavailability in conventional formulations. Among these, liposomes are useful for delivering both

hydrophilic and hydrophobic drugs, whereas phytosomes are designed for delivering hydrophilic

drug molecules mostly. For the topical application ethnosomes, transferosomes and microemulsions

show a great promise. In the better stability purpose and controlled/site specific delivery of drugs

nanoparticles and proniosomes provide a superior standard. For a long time, traditional medicines

were not considered for novel formulations due to the insufficiency on the scientific justification and

processing difficulties, like extraction, identification, proper time selection, standardization, etc. But

modern research evolving the way of newer formulations with the plant extracts and actives put

forward an enthusiastic aspect for the healthcare system with the traditional medicine. Especially the

critical traditional drugs like anticancer, antiasthmatic, antihypertensive, antidiabetic, etc., have a

great future to be explored under the newer drug delivery systems.

Abstract

Accumulating evidence suggests that protein kinase C-δ (PKC-δ) is involved in pancreatic β-cell

destruction in diabetes, in which activation of PKC-δ expressing in β-cells up-regulates pro-

inflammatory cytokines including IL-1β, TNF-α, and IFN-γ, and these cytokines induce

apoptosis in β-cells. However, little is known about the mechanism underlying this. Recently,

we demonstrated that expression level of histamine H1 receptor (H1R) gene affects the severity

of allergy symptoms. We also showed the involvement of PKC-δ signaling in the H1R up-

regulation. We explored natural resources for anti-allergic compounds that suppress H1R up-

regulation and identified some compounds including quercetin. Quercetin inhibited PKCδ

signaling by the inhibition of PKCδ Tyr311

phosphorylation, which is necessary for enzyme

activation. These findings led us to the hypothesis that quercetin is useful to alleviate diabetic

symptoms. In this study, we investigated the effect of quercetin on β-cell destruction in

streptozotocin (STZ)-induced diabetic model mice. Oral administration of quercetin (50 mg/kg)

alleviated STZ-induced diabetic symptoms. Quercetin treatment suppressed β-cell destruction

caused by STZ. PKCδ positive macrophages were infiltrated into pancreatic islet in response to

STZ treatment. A PKCδ inhibitor, rottlerin suppressed phorbol-12-myristate-13-acetate-induced

up-regulation of IL-1β expression in peritoneal macrophages. In conclusion, we have

demonstrated that treatment with STZ causes infiltrationof PKC-positive macrophages into

pancreatic islet and activation of PKCδ signaling in macrophages increases cytokine expression

and causes apoptosis in β-cells. Quercetin alleviated diabetic symptoms by suppression of

cytokine expression through the inhibiton of PKCδ signaling. Our data suggest that

macrophage-derived PKCδ is the key molecule for pancreatic β-cell destruction in STZ-induced

diabetes and this finding may contribute to the clinical application of the compounds targeted for

PKCδ signaling as new therapeutic agents for diabetes.

Abstract

Thrombus formation inside the blood vessels obstructs blood flow through the circulatory system

leading hypertension, stroke to the heart, anoxia and so on. Thrombolytic drugs are widely used

for the management of cerebral venous sinus thrombosis patients but all of these have certain

limitations. Medicinal plants and their components possessing antithrombotic activity have been

reported before; however, plants that could be used for thrombolysis has not been reported so far.

This study's aim was to evaluate the thrombolytic potential of selected plants‟ root extracts. An

in vitro thrombolytic model was used to check the clot lysis effect of four methanol soluble roots

extracts viz., Acacia nilotica, Justicia adhatoda, Azadirachta indica and Lagerstroemia speciosa

along with Streptokinase as a positive control and water as a negative control. The roots extracts

of A. nilotica, L. speciosa, A. indica, and J. adhatoda showed 15.1%, 15.49%, 21.26% and

19.63% clot lysis respectively at 5mg extract/ml NaCl solution concentration. The reference

Streptokinase showed 47.21% and 24.73% clot lysis for 30,000 I.U. and 15,000 I.U.

concentrations, respectively where 0.9% normal saline showed 5.35% clot lysis. The selected

plants‟ roots extracts possess marked thrombolytic properties that could lyse blood clots in vitro;

however, in vivo clot dissolving properties and active components responsible for clot lysis are

yet to be discovered.

Abstract

Berberine is the isoquinoline alkaloid, chiefly obtained from Berberis aristata DC (family-

Berberidaceae). It is reported to possess anticancer, antidiarrhoeal, anti-inflammatory,

antidiabetic, hepatoprotective, antimicrobial and antioxidant activities. The main objective of this

work is to evaluate the antimicrobial activity of berberine and its nanoparticles. In the present

investigation, berberine was isolated from the stem of B. aristata. The isolated berberine was

purified and characterized. Berberine loaded nanoparticles were prepared by GMO-base

polymeric method and then characterized. The berberines as well as its nanoparticles were

screened for their possible antimicrobial activity against selected bacterial and fungal strains by

disc diffusion assay method. The results of antimicrobial screening revealed that the berberine

and its nanoparticles are endowed with promising anticancer and antimicrobial properties. In

most of the cases, the nanoparticles of berberine exhibited higher antibacterial and antifungal

activities than the native berberine. Therefore, it is concluded that the berberine and its

nanoparticles are potent antimicrobial agents against the selected bacterial and fungal strains.

The development of nanoparticles of berberine is quite beneficial as evidenced from the

enhancement of its antimicrobial activity.

Abstract

Inflammatory pain is commonly associated to diabetic patients. Postprandial glucose level

reduction by inhibiting the α-amylase, an enzyme relating to carbohydrate metabolism, is a

realistic approach in diabetic patient. We focused two things in our study, one was invitro α-

amylase inhibition and another was reduction of inflammatory pain in mouse by the methanolic

leaf extracts of Lawsonia inermis. The leaves were collected, identified and methanolic extracts

were prepared. Assay was done by following the chromogenic DNSA method, and enzymatic

activity was calculated contracting a maltose standard curve. Acarbose (10µg/ml) was used as a

positive control. Acetic acid induced writhing test is started by intra peritoneal administration of

0.6% acetic acid (0.45ml/mouse) 30 min later. It causes a painful inflammatory effect. The

painful sensation of mouse, which was manifested as abdominal writhe, was counted after the

acetic acid injection. Statistical analysis was performed using Microsoft Excel 2007 and data

were compared with unpaired two tailed t-test where p value threshold was used ≤0.05 to

indicate a statistical significant. L. inermis extracts showed 29.63; 53.28; 60.97; 48.12 and 57.83

% reduction of enzymatic activity at 5; 7.5; 10; 12.5 and 15µg/ml concentrations of L. inermis

extract, respectively. Untreated one was considered as 100% enzymatic activity. Acarbose,

standard drug for α-amylase enzyme inhibition, at 10µg/ml concentration, reduced the enzymatic

activity by 76.30% compared to untreated sample. In acetic acid induced writhing test, showed

16.33,14, 11.66, 11 times mean writhing at the doses of 200, 300, 400, and 500 mg/kg of the

extract, respectively. Diclofenac, as a positive control, that showed 5 mean writhing at a dose 20

mg/kg, where as 0.9% saline showed 20.33 times mean writhing. The LD50 value of the aqueous

extract of L. inermis was found quite high, 894 mg/kg in mice. These pharmacological properties

can attribute the folkloric use of the plant in the management and control of hyperglycemia and

arthritic pain. Further investigation in human is essential to reveal its therapeutic potential.

Abstract

This study was undertaken to apply standard pharmacological and phytochemical methods in

order to establish scientific evidence of traditionally used medicinal plant‟s pharmacological use

and isolate the active constituents that may offer a local natural source of a novel therapeutic

agent. Coronary obstructive diseases having thrombotic obstruction at the artery are a major

cause of death and disability. All available thrombolytic agents still suffer significant

shortcomings, including large therapeutic doses and limited fibrin specificity. An improved

efficacy and fibrin specificity of thrombolytic therapy are now on demand. Euphorbiaceae plants

show variety of secondary metabolites including thrombolytic compounds. Therefore the aim of

present study was to screen methanolic extract of J. gossypiifolia leaves for their clot lysis

property by using an In Vitro clot lysis model. In thrombolytic activity investigation,

streptokinase was used as standard and 0.9% NaCl as negative control. This study was approved

by Noakhali Science and Technology University and regulated under the Medical Institution

Section at September, 2012. With informed consent form, human blood, collected from

volunteers (n = 10) at University Medical Institution, immediately transferred into pre-weighed

microcentrifuge tube, mixed with CaCl2 and incubated at 37°C for 45 minutes. After clot

formation, serum was removed and clot weight was determined. Plant extracts were added to

tubes with clots and incubated at 37ºC for 90 minutes. Remaining fluid was removed to weight.

The difference was expressed as % clot lysis as mean ± SEM. Statistical comparisons were made

using one-way ANOVA with Dunnett-t test. Investigation shows that at 2.5mg/mL

concentration, J. gossypiifolia exhibits highest thrombolytic activity (17.25%), where 20mg/mL

showed the least (7.723%). Standard streptokinase showed 47.218% of clot lysis at 30,000I.U

and 0.9% NaCl shows 5.353% of clot lysis. As the leaves of J. gossypiifolia, possess Glycosides,

Tannins, Phytosterols and Phenols like phytochemical constituents. This authoritative

investigation may have significant implications in cardiovascular health and may designate the

possibility of developing novel thrombolytic compounds from J. gossypiifolia, as it contains

various phytoconstituents. Further studies are afoot to isolate and characterize the responsible

compounds for thrombolytic activity.

Abstract

A healthy immune system by its self-surveillance mechanism prevents all sorts of infectious

(bacterial, viral, fungal, etc.), and eliminate/destroy cancer cells as soon as they appear. The

normal defensive capacity of the immune system is impaired by many factors and in many

conditions, such as, diabetes, cancer, AIDS, stresses, chronic insomnia, aging, lack of exercise,

poor nutrition, prolonged use of antibiotics, etc. Immunity is drastically fall in patients receiving

chemotherapy and radiotherapy. Under those immune-compromised conditions external

immunostimulants may play a significant role for the up-regulation of the immune system. The

interest in herbal medicines is growing because of its low toxicity, no side-effects, and

diversifying sources of new therapeutic agents. This study aimed to evaluate the

immunostimulating potential of four traditional Ayurvedic preparations Saribadi (SDI),

Anantamool Salsa (ANS), Mrittunjoy (MTJ) and Saribadyarista (SRT), by measuring IgM

productions and splenocytes proliferations in vitro. BALB/c female mice whole splenocytes were

treated with 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, and 4% (v/v) of each preparation, and the cells were

subcultured at 37°C for 120 hours. IgM productions in supernatants and proliferations of cells

were determined by enzyme-linked immunosorbant assay (ELISA) and 3-(4,5-dimethylthiazol-2-

yl)-2,5-diphenylterazolium bromide (MTT) assays, respectively. SDI, ANS, MTJ and SRT at a

concentration of 0.25-1.50 % (v/v) significantly augmented IgM productions. The highest

enhancement of IgM productions by SDI, ANS, MTJ and SRT were observed at the doses of

0.25, 1.50, 0.50 and 1.00%, respectively, which promoted IgM productions 3.76, 3.23, 3.29 and

4.12 times than that of control. Those preparations moderately stimulated the proliferations of

cultured splenocytes as well. The IgM productions of those preparations were not retarded by the

treatment of cells with polymixin B. Thus, the study demonstrates that the IgM production ability

of the preparations was not due to the presence of bacterial endotoxin (LPS) rather owing to the

active substance(s) in its preparations. Therefore, we can conclude that the Ayurved preparations

Saribadi, Anantamool Salsa, Mrittunjoy and Saribadyarista may be useful in strengthening

immune responses in case of insufficient or impaired immunity.

Abstract

Diabetes is a widely prevalent endocrine disorder worldwide. In previous studies, Aloe vera has

been shown to possess antidiabetic activity. Here, we aimed at discovering the underlying

mechanism of its antidiabetic action. The study was carried out in accordance to

recommendations of the “International Association for the study of Pain”. To evaluate the ability

of Aloe Vera to lower acute glucose load and basal glucose we carried out the “Glucose tolerance

test”, “Fasting Blood Glucose” respectively. The effect of sucrose absorption from various

segments of the gut (the stomach, the upper 20 cm, middle, and lower 20 cm of the small

intestine, the cecum, and the large intestine.) was determined by “Six Segment Test”. An

“Intestinal Perfusion” technique was used to study the effect of Aloe vera on intestinal absorption

of glucose in 36 h fasted non-diabetic rats. Finally, alteration of “GUT motility” was determined

to see the duration food content would be in the intestines for sugar in food to be absorbed.

Groups of data were compared using unpaired Student‟s t test and Mann–Whitney U test where

appropriate. Where data were collected over a number of time-points, analysis was based on

repeated measures ANOVA, with Bonferroni adjustment. . One-way ANOVA was performed

and pair-wise comparisons to the control group made using Dunnett‟s test. Differences were

considered significant at P<0·05. Administration of Aloe vera extract (0·5 g/kg) to normal and

type 2 diabetic rats significantly (P<0.05) improved oral glucose tolerance. It also lowered the

basal glucose level in the rats. Total remaining unabsorbed sucrose in the gastrointestinal tract of

non-diabetic and type 2 diabetic rats, following oral sucrose loading (2·5 g/kg body weight) was

not changed significantly by Aloe vera. However, the extract significantly (P<0.05) suppressed

the intestinal glucose absorption in both non-diabetic and type 2 diabetic rats. The extract also

increased (P<0.05) gastrointestinal motility in non-diabetic rats. The present findings indicate

that the Aloe vera exerts hypoglycemic effects mediated through inhibition of carbohydrate

absorption. This was achieved by reduction of sugar absorption and by increased GUT motility.

Key Words: Intestinal Perfusion, Six Segment Test, Gut Motility, Antidiabetic, Aloe Vera.

Abstract

Obesity includes the changes in the functions of adipocytes, such as the onset of insulin

resistance and adipocyte inflammation. Involving the arachidonate-cyclooxygenase (COX)

pathway, prostaglandin (PG) D2 can be produced in adipocytes and dehydrated to J2 series of

PGs including 15-deoxy-12,14

-PGJ2 (15d-PGJ2) and 12

-PGJ2, which serve as pro-adipogenic

prostanoids through the activation of PPAR. Macrophage infiltration into adipose tissue

increases with obesity, a condition associated with low-grade inflammation and insulin

resistance. Monocyte chemoattractant protein-1 (MCP-1) is known as an inflammatory

cytokines. However, regulation of MCP-1 expression through COX pathway during the life stage

of adipocytes has not been studied well. Here we studied the role of COX inhibitors in

adipogenesis and also aimed at the investigation of MCP-1 expression during adipogenesis with

a vision to explore whether the J2 series prostaglandins have pervasive effect on expression of

proinflammatory cytokines in cultured adipocytes. 3T3-L1 cells were grown, differentiated and

maturated in suitable culture media along with or without different treatment ( Aspirin,

prostaglandins). the end of maturation of adipocytes, total RNA was extracted and analyzed for

the expression of adipgenic genes. Our results revealed that COX inhibitors negatively regulate

the adipogenesis in cultured adipocytes. MCP-1 was highly expressed during the maturation

phase of adipogenesis. Furthermore, expression of MCP-1 was regulated by the treatment with

either of 12

-PGJ2 or 15d-PGJ2. Although 12

-PGJ2 was slightly less potent than 15d-PGJ2, each

of these PGJ2 series rescued effectively the gene expression of MCP-1 that was attenuated in the

presence of aspirin. Our findings indicate that adipocyte inflammation is regulated by MCP-1

expression through the COX pathway in cultured adipocytes.

Abstract

Amlapittantaka Ras (APT) is an Ayurvedic preparation used as a traditional medicine in the

treatment of hyperacidity in the rural population. To find out the toxicological characteristic of

APT, it was administered chronically to the male rats at a dose of 400 mg/kg. After 27 days of

chronic administration of the APT preparation the following toxicological changes were noted.

In the male rats there was decrease in the Total protein (5.19 % decr.) content in the plasma

which was not significantly (p=0.372) different from their corresponding control values. In the

male rats there was negligible decrease in the triglyceride level (4.84 % decr.) (p=0.916) and

VLDL (4.84 % decr.) (p=0.916). Whereas negligible increase in the total cholesterol (2.32 %

incr.) (p=0.615) and LDL (4.57 % incr.) (p=0.621) was noted. Though not statistically

significant (p=0.151) yet prominent increase was noted in the case of HDL (48.34 % incr.)

content in the plasma. None of the changes were statistically significantly different from their

corresponding control values. The decrease in Total cholesterol /HDL ratio (19.13 % decr.)

(p=0.390) and the decrease in LDL/HDL ratio (28.33 % decr.) (p=0.206) were not statistically

significantly different from their corresponding control values. APT increased the bilirubin level

(29.20% incr.) which was not statistically significant (p=0.661). There was an increase in the

creatinine (60.60% incr.) content in plasma in the APT treated male rats which was not

statistically significant yet it was noticeable (p=0.089). On the contrary, a decrease of urea level

(19.09% decr.) in the plasma was noted in comparison to their control group, the decrease was

not statistically significant though it was noticeable too (p=0.094). The increase in Urea /

Creatinine ratio (113.41 % incr) was statistically significant (p=0.019). APT caused 9.67%

decrease in plasma uric acid which was not statistically significant (p=0.720).

Abstract

Echchabhedii Rosh (EBR) is an Ayurvedic preparation used as a traditional medicine in the

treatment of ascites in the rural population. To find out the toxicological characteristic of EBR, it

was administered chronically to the male rats at a dose of 400 mg/kg. After 28 days of chronic

administration of the EBR preparation the following toxicological changes were noted. In the

study, the total protein content in the plasma was decreased (7.99 % decr.) in the EBR treated

male rats. The decrease in total protein was not statistically significant yet it was noticeable

(p=0.073). Interestingly, the albumin content was increased (14.87 % incr.) and the globulin

content was decreased (29.05 % decr.) though not significantly in both the cases (respectively

p=0.483 and p=0.410) in EBR treated male rats. In the male rats there was all throughout

decrease in the triglyceride level (47.00 % decr.), total cholesterol (24.03 % decr.), VLDL (52.11

% decr.) and LDL (28.17 % decr.). The only exception was an increase in HDL (239.05 % incr.)

content in the plasma. After chronic administration of EBR the triglyceride level was 47.00 %

(p=0.229) decreased in male rats group which was not statistically significant. In this

investigation statistically significant (p=0.016) decrease of plasma total cholesterol level in the

EBR treated male rats was observed in comparison to control. Also a decrease in the VLDL and

LDL content in the plasma was noted. Statistically insignificant decreases were observed in case

of VLDL (52.11% decr.) (p=0.157) and though not significant yet noticeable decrease was

observed in case of LDL (28.17% decr.) (p=0.054) from their corresponding control, whereas

239.05% increase of HDL level was noticed though which was not statistically significant

(p=0.259). After chronic administration of Echchabhedii Rosh (EBR) to the male rats an increase

of bilirubin level (280.0 % incr.) in the plasma was noted in comparison to their control group

which was not statistically significant but yet it was noticeable (p=0.055). Also a statistically

insignificant though noticeable decrease in the urea (21.34% decr.) content in plasma was noted

(p=0.077). EBR treated male rats demonstrated 50.60 % increase in plasma uric acid content

which was not statistically significant (p=0.102) though it was noticeable. In the male rats there

was a statistically insignificant 14.87 % increase in the sGPT (p=0.483) and also a statistically

insignificant 10.05 % decrease in the sGOT activity in the plasma (p=0.685).

Abstract

Chaturmukh Ras (CTM) is an Ayurvedic preparation used as a traditional medicine in the

treatment of epilepsy in the rural population. To find out the toxicological characteristic of CTM,

it was administered chronically to the male rats at a dose of 400 mg/kg. After 27 days of chronic

administration of the CTM preparation the following toxicological changes were noted. In the

male rats there was decrease in the Total protein (9.23 % decr.) content in the plasma which was

though not statistically significantly different from their corresponding control values yet it was

noticeable (p=0.068). In the male rats there was statistically significant decrease in the total

cholesterol (18.85 % decr.) (p=0.013) and in the case of LDL (31.04 % decr.) though the

decrease was not statistically significant, yet it was noticeable (p=0.097). Whereas increase was

noted in the triglyceride level (4.96 % incr.) (p=0.919), VLDL (23.13 % incr.) (p=0.618) and

HDL (81.09 % incr.) (p=0.194) content in the plasma. None of the increase in the triglyceride

level, VLDL and HDL content were significantly different from their corresponding control

values. The decrease in Total cholesterol /HDL ratio (69.67 % decr) was statistically significant

(p=0.020) but the decrease in LDL/HDL ratio (80.69 % decr.) though not statistically significant

yet it was noticeable (p=0.061). CTM increased bilirubin level (89.20% incr.) in the plasma

which was not statistically significant (p=0.399). There was increase in the creatinine (23.97%

incr.) (p=0.518) content in plasma in the CTM treated male rats. On the contrary, a negligible

decrease of urea level (1.04% decr.) (p=0.920) in the plasma was noted in comparison to their

control group. Overall an increase in Urea / Creatinine ratio (36.59 % incr) (p=0.395) was noted.

None of these changes were statistically significantly different from their corresponding control

values. CTM did not reveal any change in the plasma uric acid content.

Abstract

Naradiya Mahalaksmi Bilas (NMB) which is an Ayurvedic preparation is used as „traditional

medicine‟ in the treatment of „sinusitis‟ amongst the rural population in India, Bangladesh,

Srilanka, Nepal, Bhutan and Pakistan. With an objective to examine the toxicological

characteristic of NMB, it was administered chronically up to 43 days to the male rats at a dose of

400 mg/kg. After 43 days of chronic administration of the NMB preparation to the male rats the

following toxicological changes were noted. The study shows the Total Protein percentage (0.04

% incr.) in the NMB treated male rats ,which indicates that there was almost no change in the

Total Protein. The albumin content was very highly significantly (p=0.001) decreased (34.33 %)

and the globulin content was very highly significantly (p=0.001) increased (35.91 %) in NMB

treated male rats. The decrease (50.76%) in the Albumin / Globulin ratio was statistically very

highly significantly different from their corresponding control values (p=0.001). There was all

over decrease in the triglyceride level (20.00 % decr.), total cholesterol (4.51 % decr.), LDL

(81.06 % decr.) and HDL (33.13 % decr.) in the NMB treated male rats. Increase in plasma

VLDL (90.48 % incr.) level was only an exceptional occurrence. Chronic administration of

NMB decreased the triglyceride level by 20.00 % in male rats group which was statistically

insignificant (p=0.349). At the same time, a decrease in the LDL and HDL content in the plasma

was also noted. Significant decrease were observed in case of LDL (81.06% decr.) (p=0.014) and

statistically insignificant yet noticeable (p=0.088) decrease were observed in case of HDL

(33.13% decr.) from their corresponding control values , whereas 90.48% increase of VLDL

level was noticed, which was not statistically significant (p=0.164). The increase in Total

cholesterol /HDL ratio (81.64 % incr.), though, not statistically significant yet it was noticeable

(p=0.087) and the decrease in LDL/HDL ratio (56.19 % decr.) was not statistically significant

(p=0.248). A highly significant increase in the plasma urea level (23.64%) was noted (p=0.001).

The increase in Urea/Creatinine ratio (26.91 % incr.) was statistically insignificant but noticeable

(p=0.104).

Abstract

Pradarantak Ras (PDR) is an Ayurvedic preparation used as a traditional medicine in the

treatment of leucorrhoea in the rural population. To find out the toxicological characteristic of

PDR, it was administered chronically to the male rats at a dose of 400 mg/kg. After 43 days of

chronic administration of the PDR preparation the following toxicological changes were noted.

In the study, there was almost no change in the Total protein (0.34 % decr.) in the PDR treated

male rats. Obviously the decrease in the Total protein (p=0.938) was not significantly different

from their corresponding control values. Interestingly, the albumin content was significantly

(p=0.037) decreased (13.92 %) and the globulin content was insignificantly (p=0.577) increased

(5.18 %) in PDR treated male rats. The decrease (13.48%) in the Albumin / Globulin ratio was

not significantly different from their corresponding control values (p=0.373). In the male rats

there was all throughout decrease in the triglyceride level (87.21 % decr.), total cholesterol

(22.57 % decr.), VLDL (87.93 % decr.), LDL (28.48 % decr.) and HDL (6.30 % decr.) content in

the plasma. After chronic administration of PDR the triglyceride level was 87.21 % (p=0.001)

decreased in male rats group which was statistically very highly significant. In this investigation

though not statistically significant yet noticeable (p=0.082) decrease of plasma total cholesterol

level in the PDR treated male rats was observed in comparison to control. Also a decrease in the

VLDL and LDL content in the plasma was noted. Very highly significant decrease were

observed in case of VLDL (87.93% decr.) (p=0.001) and statistically insignificant decrease were

observed in case of LDL (28.48% decr.) (p=0.211) from their corresponding control, whereas

only 6.30% decrease of HDL level was noticed which was not statistically significant (p=0.701).

The decrease in both Total cholesterol /HDL ratio (11.39 % decr.) (p=0.527) and in LDL/HDL

ratio (45.84 % decr.) (p=0.833) was not statistically significantly different from their

corresponding control values. After chronic administration of PDR to the male rats a statistically

significant (p=0.032) decrease of bilirubin level (78.01% decr.) in the plasma was noted in

comparison to their control group. There was an increase in the plasma creatinine (4.61%) in the

PDR treated male rats, though this increase was not significant (p=0.658). On the contrary, a

very highly significant increase in the urea (43.09%) content in plasma was noted (p=0.001). The

increase in Urea / Creatinine ratio (57.09 % incr) was statistically very highly significant

(p=0.001).

Abstract

Brihat Bangesvar Ras (BBG) is an Ayurvedic preparation used as a traditional medicine in the

treatment of haematuria in the rural population. To find out the toxicological characteristic of

BBG, it was administered chronically to the male rats at a dose of 400 mg/kg. After 27 days of

chronic administration of the BBG preparation the following toxicological changes were noted.

In the male rats there was decrease in the Total protein (10.04 % decr.) content in the plasma

which was not significantly (p=0.278) different from their corresponding control values. In the

male rats there was all throughout increase in the triglyceride level (359.64 % incr.), total

cholesterol (3.93 % incr.), VLDL (178.30 % incr.) and HDL (5.11 % incr.). The only exception

was a decrease in LDL (18.69 % decr.) content in the plasma. After chronic administration of

BBG the triglyceride level was prominently (359.64 %) increased in male rats group, although it

was not statistically significant (p=0.164). In this investigation also statistically insignificant

(p=0.635) increase of plasma total cholesterol level in the BBG treated male rats was observed in

comparison to control. Also an increase in the VLDL and HDL content in the plasma was noted.

Insignificant increases were observed in both VLDL (178.30% incr.) (p=0.263) and HDL (5.11%

incr.) (p=0.895) in comparison to their corresponding control, whereas 18.69% decrease of LDL

level was noticed which was not statistically significant (p=0.185). The decrease in Total

cholesterol /HDL ratio (25.31 % decr.) (p=0.346) and the decrease in LDL/HDL ratio (46.63 %

decr.) (p=0.194) were not statistically significantly different from their corresponding control

values. BBG decreased the bilirubin level (35.80% decr.) which was not statistically significant

(p=0.377). There was increase in the creatinine (26.54% incr.) (p=0.484) content in plasma in the

BBG treated male rats. On the contrary, a decrease of urea level (12.36% decr.) (p=0.336) in the

plasma was noted in comparison to their control group. Overall an increase in Urea / Creatinine

ratio (53.66 % incr) (p=0.216) was noted. BBG caused 26.34% decrease in plasma uric acid

which was not statistically significant (p=0.248).

Abstract

Sarivadi Vati (SBD) is an Ayurvedic preparation used as a traditional medicine in the treatment

of otitis media in the rural population. To find out the toxicological characteristic of SBD, it was

administered chronically to the male rats at a dose of 400 mg/kg. After 43 days of chronic

administration of the SBD preparation the following toxicological changes were noted. In the

study, the total protein content in the plasma was increased (4.89 % incr.) in the SBD treated

male rats. The increase in total protein was not significant (p=0.138). Interestingly, the albumin

content was statistically highly significantly (p=0.003) decreased (16.94 % decr.) and the

globulin content was highly significantly (p=0.006) increased (44.29 % incr.) in SBD treated

male rats. The decrease (37.03%) in the Albumin /Globulin ratio was statistically highly

significantly different from their corresponding control values (p=0.003). In the male rats there

was all throughout decrease in the triglyceride level (7.95 % decr.), total cholesterol (21.03 %

decr.), VLDL (7.95 % decr.) and LDL (44.30 % decr.), with the exception with HDL (7.63 %

incr.) content in the plasma. After chronic administration of SBD the triglyceride level was 7.95

% (p=0.592) decreased in male rats group which was not statistically significant. In this

investigation statistically significant (p=0.018) decrease (21.03 % decr.) of plasma total

cholesterol level in the SBD treated male rats was observed in comparison to control.

Statistically insignificant decrease was observed in case of VLDL (7.95% decr.) (p=0.592), on

the contrary insignificant increase were observed in case of HDL (7.63% incr.) (p=0.638) from

their corresponding control, whereas only 44.30% decrease of LDL level was noticed which

though not statistically significant, yet it was noticeable (p=0.093). The decrease in Total

cholesterol /HDL ratio (23.29 % decr.) (p=0.049) and the decrease in LDL/HDL ratio (30.63 %

decr.) (p=0.015) were both statistically significantly different from their corresponding control

values. After chronic administration of Sarivadi Vati (SBD) to the male rats a decrease of

bilirubin level (32.75% decr.) in the plasma was noted in comparison to their control group

which was not statistically significant (p=0.484). There was a statistically insignificant increase

in the creatinine (4.76% incr.) (p=0.611) content in plasma in the SBD treated male rats. On the

contrary, a statistically very highly significant (p=0.001) decrease of urea level (39.52% decr.) in

the plasma was noted in comparison to their control group. The decrease in Urea / Creatinine

ratio (46.28 % decr) was statistically significant (p=0.032).

Abstract

Tamra Bhasma (TMR), an widely used Ayurvedic preparation as a traditional medicine in the

treatment of anemia in the rural population of bangladesh. In this study our objective is to find

out the toxicological characteristic of TMR and it was administered chronically to the male rats

at a dose of 400 mg/kg. After 46 days of chronic administration of the TMR preparation the

following toxicological changes were noted. In the study, the total protein content in the plasma

was decreased (16.37 %) in the TMR treated male rats. The decrease in total protein was

statistically highly significant (p=0.004). On the contrary, the albumin content was significantly

(p=0.026) increased (41.74 %) in TMR treated male rats. In the male rats though there was a

negligible decrease noted in the triglyceride level (1.67 % decr.) (p=0.964) and prominent

decrease in the VLDL (34.45 % decr.) (p=0.333) content in the plasma, the decreases in both of

the cases were not statistically significant. Whereas statistically highly significant increase in the

total cholesterol (149.52 % incr.) (p=0.002), and in the case of LDL though not significant yet

noticeable increase (58.11 % incr.) (p=0.094) was noted, besides in the case of HDL no

statistical increase in HDL (14.66 % incr.) (p=0.435) content in the plasma was noted. The

increase in Total cholesterol /HDL ratio (145.12 % incr) was statistically highly significant

(p=0.007) and the increase in LDL/HDL ratio (72.08 % incr.) was statistically highly significant

(p=0.008). After chronic administration of Tamra Bhasma (TMR) to the male rats an increase of

bilirubin level (10.07% incr.) in the plasma was noted in comparison to their control group

which was not statistically significant (p=0.820). There was an decrease in the plasma creatinine

(11.76% decr.) in the TMR treated male rats, and this decrease was not significant (p=0.216).

TMR caused about 31.65% decrease in plasma uric acid which was statistically significant

(p=0.032). On the other hand, there is a statistically highly significant increase in the sGOT

activity (47.73% incr.) (p=0.005) and a statistically very highly significant increase in the sGPT

activity (72.37% incr.) (p=0.001) in the plasma was noted. Whereas there was a decrease in the

ALK-Pase activity (4.42% decr.) (p=0.717) which was not statistically significantly different

from the control male rats. A statistically significant increase in the LDH activity (63.02% incr.)

(p=0.021) in the plasma was noted.

Abstract

Praval bhasma (PBL) is an Ayurvedic preparation used as a traditional medicine in the treatment

of osteoporosis in the rural population. To find out the toxicological characteristic of PBL, it was

administered chronically to the female rats at a dose of 400 mg/kg. After 52 days of chronic

administration of the PBL preparation the following toxicological changes were noted. In the

female rats there was increase in the Total protein (10.20 % incr.) and the Globulin (37.93 %

incr.) content in the plasma. There was almost no change in the Albumin (1.36 % incr.). None of

the increase in the Total protein (p=0.170), in the Albumin (p=0.881) and the Globulin (p=0.207)

content were significantly different from their corresponding control values. The decrease

(35.66%) in the Albumin / Globulin ratio was not significantly different from their

corresponding control values (p=0.200). In the female rats there was all throughout increase in

the triglyceride level (14.26 % incr.), total cholesterol (77.27 % incr.), VLDL (14.26 % incr.) and

LDL (232.78 % incr.). After chronic administration of PBL the triglyceride level was 14.26 %

(p=0.190) increased in female rats group which was not statistically significant. In this

investigation statistically very highly significant (p=0.001) increase of plasma total cholesterol

level in the PBL treated female rats was observed in comparison to control. Also an increase in

the VLDL and LDL content in the plasma was noted. Statistically insignificant increase were

observed in case of VLDL (14.26% incr.) (p=0.190) and highly significant increase were

observed in case of LDL (232.78% incr.) (p=0.002) from their corresponding control. After

chronic administration of Pravala Bhasma (PBL) to the female rats a increase of bilirubin level

(27.53% incr.) in the plasma was noted in comparison to their control group which was not

statistically significant (p=0.849). There was a decrease in the creatinine (46.50% decr.) content

in plasma in the PBL treated female rats which was statistically highly significant (p=0.009).

PBL caused about 512.91% increase in plasma uric acid which was statistically significant

(p=0.038). In the female rats a noticeable increase in the sGOT activity (24.17% incr.) (p=0.079)

and a noticeable increase in the sGPT activity (27.12% incr.) (p=0.066) in the plasma was noted

though in both the cases they were not statistically significant but as mentioned before were

noticeable in both of the cases. Whereas there was a statistically highly significant decrease in

the ALK-Pase activity (28.45% decr.) (p=0.009) and a statistically very highly significant

increase in the LDH activity (113.30% incr.) (p=0.001) in the plasma.

Abstract

Banga Bhasma (BNG) is an Ayurvedic preparation used as a traditional medicine in the

treatment of leucorrhoea in the rural population. To find out the toxicological characteristic of

BNG, it was administered chronically to the female rats at a dose of 400 mg/kg. After 52 days of

chronic administration of the BNG preparation the following toxicological changes were noted.

In the study, the total protein content in the plasma was increased (3.88 %) in the BNG treated

female rats. The increase in total protein was not significant (p=0.504). Interestingly, the albumin

content was statistically insignificantly (p=0.346) increased (6.82 %) and the globulin content

was insignificantly (p=0.318) decreased (59.02 %) in BNG treated female rats. The negligible

(0.16%) increase in the Albumin / Globulin ratio was not significantly different from their

corresponding control values (p=0.996). In the female rats there was all throughout increase in

the triglyceride level (3.52 % incr.), total cholesterol (95.50 % incr.), VLDL (3.52 % incr.) and

LDL (60.63 % incr.) content in the plasma. After chronic administration of BNG the triglyceride

level was 3.52 % (p=0.631) increased in female rats group which was not statistically significant.

In this investigation statistically very highly significant (p=0.001) increase of plasma total

cholesterol level in the BNG treated female rats was observed in comparison to control. Also an

increase in the VLDL and LDL content in the plasma was noted. Statistically insignificant

increase was observed in both the cases of VLDL (3.52% incr.) (p=0.631) and LDL (60.63%

incr.) (p=0.160) from their corresponding control. After chronic administration of BNG to the

female rats an increase of bilirubin level (92.55% incr.) in the plasma was noted in comparison to

their control group which was not statistically significant (p=0.354)There was a negligible

decrease in the plasma creatinine (1.49%) in the BNG treated female rats, and this decrease was

not significant (p=0.865). BNG caused 355.92% increase in plasma uric acid which was

statistically very highly significant (p=0.001). In the female rats a negligible increase in the

sGOT activity (0.66% incr.) (p=0.946) and a prominent increase in the sGPT activity (20.54%

incr.) (p=0.162) in the plasma was noted though in both the cases they were statistically

insignificant. Whereas there was a statistically significant decrease in the ALK-Pase activity

(23.62% decr.) (p=0.023) and a statistically significant increase in the LDH activity (38.15%

incr.) (p=0.028) in the plasma.

Abstract

Tryodashanga Guggulu (TR-G), a classical Ayurvedic preparation which is used in

musculoskeletal disorders, was studied for its effect on different hormonal parameters after

chronic administrations for 45 days to male Sprague-Dawley rats. There is a statistically very

highly significant (p=0.001) elevated serum total T3 (Triodothyronine) level. [ 650.0 %

elevation]. There is an [4.95 %] elevation in the Free fraction of T3 (Triodothyronine) level, the

elevation though not significant yet it was prominent (p=0.490). There is a [5.51 %] lowering in

the seum Total T4 level, the lowering though not significant yet it was prominent (p=0.393).

Abstract

Panchatikta Ghrita Guggulu (PTK-G) an Ayurvedic preparation used as a traditional medicine in

the treatment of skin diseases in the rural population and is included in Bangladesh National

Ayurvedic formulary. A clinical study was conducted to find out the efficacy in eczema. PTK-G

was administered orally at a dose of 500 mg capsules thrice daily for a period of 6 weeks in a

single blind, quasi random clinical study comprising of 20 patients (6 males and 14 females).

Hematological, biochemical and symptomatic evaluation were done. PTK-G reduced itching and

vesicle formation. A total absence of scaling, oozing, erythema and fissure were noted.

Haematological findings reveal lowering of ESR, decrease in total count (TC) of WBC with a

noteworthy decrease in lymphocyte and eosinophil count ((p=0.015)). Clinical chemistry

revealed that total cholesterol was decreased ↓13.05%, which was not significant but it was

noticeable (p= 0.100). LDL and TG were noticeably decreased (↓15.12% and ↓15.56%), though

they were not statistically significant (p=0.177 and p= 0.237). Blood urea, creatinine, uric acid,

sGOT, sGPT, blood sugar and serum alkaline phosphatase level were decreased. Lowering of

hemoglobin level was noted as side effect. Increase in itching and oozing were noted after the

initial 3 to 4 days of administration which was subsided after the 2nd

week and subsequently

onwards. Caution should be taken in anemia, Diabetes mellitus and during co-administration of

any anticoagulant, blood thinning, anti-diabetic drugs or lipid lowering agents as it may

potentiate or deplete the activity of these drugs or herbs respectively.

Abstract

Villagers and suburban dwellers generally rely on folk medicinal healers (Kavirajes) to treat

different ailments. Various ethnomedicinal plants are used for diverse ailments, which remain

undocumented as well as undiscovered as a source of novel active pharmaceutical ingredients.

Our survey points out to the conservation of ethnomedicinal and ethnobotanical knowledge,

which is being lost day by day and subsequent scientific validation of this knowledge. The

survey was conducted using a semi-structured questionnaire. The information was collected from

fifteen folk medicinal healers of six villages of Tangail (24ο 15

ethnobotanical survey was carried out from April 2012 to June 2013. SPSS statistics was used to

analyze the obtained data. One hundred and seven medicinal plants were found to be used as

cure for fifty two ailments. Among them, twenty four plants were used for treating intestinal

disorders, thirteen for respiratory diseases, fifteen for fever and rheumatic pains, twelve for

diabetes, five for jaundice, twelve for male and female sexual disorder and so on. The most

frequently utilized plant parts were the leaf (37%), root (13%), fruit (17%), seed (10%), Stem

(8%). The medicinal plant usages by the traditional healers revealed that many ailments were

treated by a single plant while many plants were used for treating a single ailment. It was also

found that these healers did not have proper knowledge of appropriate dosages for the treatment

of a particular ailment and it varied from healers to healers. Apart from these, the healers were

not keen to provide any information and therefore, the tendency of healers not to disclose

information puts the risk of eroding the wealth of ethnomedicinal knowledge over time.

Abstract

Xanthium indicum (Koenig) belonging to the family Asteraceae, and has been used as flock

medicine for many years. This study has been designed to investigate for preliminary

Phytochemical screening and evaluation of their Pharmacological activities in various

pharmacological models. like anthelmintic activity, brine shrimp lethality bioassay, in-vitro

thrombolytic activity and antioxidant activity. The crude methanolic extract was screened for

different phytochemicals. Then the crude extract is investigated for the pharmacological activity.

Crude methanolic extract was administered to different model to screen the pharmacological

activities. The anthelmintic assay was done which displayed significant activity against the

Phertima prosthuma .The experiment showed very significant result compare with standard(

Piperazine citrate). A preliminary toxicological investigation of methanolic extract performed by

brine shrimp bioassay technique. The LC50 value of crude extract showed moderate result

(1.345µg/ml) comparison with positive control vincristine sulphate (with LC50 0.839 µg/ml). In

evaluation of in vitro thrombolytic activity of methaolic crude extract through in-vitro clot lysis

model, the extract induced slight (p> 0.05) clot lysis of human blood with 17. 52% at 2.5

mg/ml, 13.19 % at 5mg/mL ; 11.58% at10mg/mL and 9.11 % at 20 mg/ml compare to control

where the standard thrombolytic drug Streptokinase (30,000 IU and 15000 IU) evoked a

significant clot lysis activity 47.22 % and 24.73% clot lysis respectively. The antioxidant

activity of the crude methanolic extract was observed by determining total phenolic content

and1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays. Result calculated as slight

Abstract

Ethnobotany is the scientific study of human interactions with plants and environment. This

includes the study how traditional and modern cultures across the globe interact or have

interacted with plants. The incidence of Diabetes is growing rapidly in many countries in the

world and very common in developing countries like Bangladesh. Around 180 million people are

afflicted with diabetes worldwide and the prevalence is expected to more than double by the year

in 2030. Diabetes is a heterogeneous group of syndromes characterized by an elevation of blood

glucose level caused by a relative or absolute deficiency of insulin. Diabetes can cause serious

hyperglycemia if it is untreated, take the form of diabetic retinopathy, diabetic nephropathy,

diabetic neuropathy and cardiovascular complications such as heart attack, kidney disease and

renal failure. With diabetes being a widespread threat to humanity, plant kingdom plays an

important role in diabetes ailments. Modern allopathic medicine has no known cure for the

diabetic patients. Therefore the present ethobotananical survey was carried out among the folk

medicinal practitioners of Tangail district in Bangladesh for documentation of the indigenous

medicinal plants used by them for the treatment of diabetes as well as to find out scientific

validation of their usages over the years. It was found that the folk medicinal practitioners used a

number of medicinal plants to lower the level of blood glucose of the patients without any

knowledge on the mechanism of action of these plants.

Abstract

Diabetes is a widely prevalent endocrine disorder worldwide. Catharanthus roseus has been

shown to possess antidiabetic activity. In our study, we aimed at discovering the underlying

mechanism of its antidiabetic action. The study was carried out in accordance to

recommendations of the international Association for the study of Pain. To evaluate the ability of

Catharanthus roseus to lower acute glucose load and basal glucose we carried out the “Glucose

tolerance test”, “Fasting Blood Glucose” respectively. The effect of sucrose absorption from

various segments of the gut (the stomach, the upper 20 cm, middle, and lower 20 cm of the small

intestine, the cecum, and the large intestine.) was determined by “Six Segment Test”. An

“Intestinal Perfusion” technique was used to study the effect of Catharanthus roseus on

intestinal absorption of glucose in 36 h fasted non-diabetic rats. Finally alteration of “GUT

motility” was determined to see how long the food content would be in the intestines for sugar

in food to be absorbed. Groups of data were compared using unpaired Student‟s t test and Mann–

Whitney U test where appropriate. Where data were collected over a number of time-points,

analysis was based on repeated measures ANOVA, with Bonferroni adjustment. . One-way

ANOVA was performed and pair-wise comparisons to the control group made using Dunnett‟s

test. Differences were considered significant at P<0·05. Administration of Catharanthus roseus

(0·5 g/kg body weight) to normal and type 2 diabetic rats significantly (P<0.01) improved oral

glucose tolerance. Basal blood level remained unaffected. Total remaining unabsorbed sucrose in

the gastrointestinal tract of non-diabetic and type 2 diabetic rats, following oral sucrose loading

(2·5 g/kg body weight) was significantly (P<0.05) increased by Catharanthus roseus extract.

The extract significantly (P<0.05) suppressed the intestinal glucose absorption in both non-

diabetic and type 2 diabetic rats. The extract also increased gastrointestinal motility (P<0.01).The

present findings indicate that the Catharanthus roseus exerts hypoglycemic effects mediated

through inhibition of carbohydrate absorption and by shortening the GUT transit time of food

substance. It probably does not have any insulin secretagogue action since basal glucose level

remained unchanged.

Abstract

Desmodium Pulchellum Benth(Fabaceae), used in variety of ailments in folk medicinal practices

by the tribes of Malays, Deori in different regions of Philippines,Java (Indonesia), India, was

investigated for its antipyretic andin vitro thrombolytic potential.Ethanolic root extract of

Desmodium Pulchellum Benth was administered at the dose of 500 mg\kg (p.o) by suspending

the extract in distilled water. Brewer's yeast suspension (10 mg/kg) was used as a fever inducing

agent in this experiment. The clot lysis activity was assessed by addition of the test material to

the pre-clotted blood and incubation for 90minutes at 37°C and was expressed % lysis of clot.

The ethanolic root extract and its partitionates at concentration 10mg/ml were tested.The

ethanolic root extract of Desmodium Pulchellum Benth exhibited statistically highly significant

(p < 0.001) antipyretic effect 3 hours after administration in Brewer‟s yeast induced pyrexia in

Long Evansrats. Addition of 100µl standard streptokinase(SK), a positive control (30,000

I.U.), to the clots and subsequent incubation for 90 minutes at 37°C, showed 66.84%

lysis of clot.At the same time, distilled water was treated as negative control which

exhibited negligible lysis of clot (3.87%). In this study, the methanol soluble

fraction exhibited highest thrombolytic activity (84.13%) which showed greater activity

than standard. The ethanolic extract has exhibited lysis of 41.95%.However, other partitionates

also showed significant thrombolytic activity such as hexane soluble fraction (49.89%) and

aqueous soluble fraction (49.89%).These results show that ethanol extract ofDesmodium

Pulchellum Benthhas antipyretic and thrombolytic activity.

Abstract

In this study essential oil composition, antioxidant and cytotoxic properties of the flowers of

Alstonia scholaris (L.) R. Br. was investigated. The chemical composition of the oil was

analyzed by GC-MS. The antioxidant potential was evaluated using two separate methods,

inhibition of free radical 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide radicals

scavenging activities assay. Furthermore, the total phenolic compound was determined and

expressed as gallic acid equivalent of dry weight of sample. The cytotoxicity of the oil was also

determined through the brine shrimp toxicity assay. Twenty-six compounds representing 92.84%

of the total oil were identified. In the first case of antioxidant potential assay, the IC50 (inhibitory

concentration) value of the oil was 12.1 ± 1.2 μg/mL. Among the extracts, the strongest activity

was exhibited by the methanol extract (IC50:15.36 ± 1.3). In the superoxide radicals scavenging

activities assay, the oil showed the strongest activity (IC50: 20.83 ± 0.3l μg/mL) and methanol

extract displayed stronger activity (IC50: 30.47 ± 0.6 μg/mL) than other extracts. The LC50 (LC,

lethal concentration) value of 2.56 ± 0.13 μg/mL indicated that the oil was highly toxic. It is

suggested that the active compounds of the Alstonia scholaris flower exhibit potential

antioxidant and cytotoxic properties. These substances can be considered as a potential

antioxidant and cytotoxic agents as well as imminent candidate for cancer therapy.

Abstract

Cephalosporins are a class of β-lactam antibiotics originally derived from the fungus

Acremonium, which was previously known as "Cephalosporium". It would be beneficial if the

development process of cephalosporin is well understood by thorough analysis (catechol and

isoxazolidin cephalosporin) and its subsequent commercialization process in the realistic sense.

Clear concepts of classical and modern approach and importance of modern process of

cephalosporin development (phytopharmacy, raw material supply, identity test, house control,

chemical approach, preclinical-clinical development, patent policy) and commercialization

(optimistic way) could pave the way for more accurate treatment, sustainable and rational uses of

medicines.

Abstract

Identification and validation of key biomolecules related to diseases has always been the first

step towards Drug Designing. Although tradition approaches have already proved to be

successful for a limited spectrum of diseases, distinguishing the best target for complex disease

such as cancer, neurodegenerative or cardiac diseases, muscular dystrophies, etc is still

somewhat daunting. Often these fatal diseases are governed by a complex network of

interconnected biomolecules (proteins, RNAs) and their highly regulated interaction and

functional profile makes target identification and validation even challenging. Over the years

Revolutionary advancement has been achieved in the field of omics studies such as Genomics,

Proteomic and Metabolomics and some other emerging fields such as systems biology. Recent

works has already confirmed that integration of genomics and proteomics study with basic

clinical sciences can tremendously aid to identify novel target for specific disease by comparing

healthy and diseased sample in genomic, proteomic or metabolic level. System level analysis of

these biomolecular network not only helps to narrow down key molecules related to the disease

along with their interacting partners, they also assist to screen out the most suitable target for

drug design based on interaction hierarchy. Simultaneously, in silico drug design approaches

which utilize modern bioinformatics tools and detailed structural information of a wide array of

biomolecules can drastically enhance drug design process. Undoubtedly these high throughput

studies have already raised a great deal of hope and such multidisciplinary approaches will

definitely render us with the most effective drugs to fight against all prevailing life threatening

diseases in near future.

Abstract

Folk medicinal practitioners, well known as Kavirajes, form the primary line of health-care

among a substantial section of the rural and urban population of Bangladesh. They rely on

administration of medicinal plants for treatment of diseases. Since the medicinal plants used by

the Kavirajes can differ widely even between adjoining areas, it was the objective of the present

study to conduct an ethnomedicinal survey among the selected Kavirajes of different villages at

Nalitabari Upazilla situated in Sherpur district ,Bangladesh. Informed consent was obtained and

interviews were conducted of the Kavirajes with the help of a semi-structured questionnaire and

the guided field-walk method. Plant specimens as pointed out by them were collected and

identified at the Bangladesh National Herbarium. It was observed that the Kavirajes of the

selected areas used a total of 115 plants distributed into 68 families for treatment of various

ailments. The Liliaceae family provided the largest number of species (6); followed by the

Cucarbitaceae , Fabaceae , Zingiberaceae family (5); Rosaceae , Myrtaceae , Apiaceae (4) and

other of the families contributed single plant. Of the total 160 uses found in the present survey,

leaves formed the most frequently used plant part (26.87%), followed by Fruits (18.12%) ,seeds

(16.25%) , roots (13.75%) ,stems (11.27%), flower( 6.23%) ,Bark ( 5%) and whole plant (2.6%).

Most of cases, a single plant part was used for treatment of any given ailment. Most of the plants

were used to treat common ailments such as respiratory tract problems, gastrointestinal disorders,

fever and loss of hair, vomiting, menstrual problems, skin disorders, dental diseases, cracked

foot, bleeding, insect bites and bone fracture. However, a number of plants were also used to

treat more complicated ailments like cardiovascular disorders, hepatic disorders, mental disease,

epilepsy, piles, leprosy, diabetes and cancer or tumors. Folk medicine in Bangladesh has a

history of usage going back thousands of years thus possess considerable potential for further

scientific research for discovery novel compounds that may serve as the source of effective

modern drugs.

Abstract

Bifidobacteria are important constituents of the intestinal microflora of humans and animals.

These organisms are the predominant group of bacteria in the normal intestinal flora of healthy

breast-fed newborns where they constitute more than 95% of the total population. The objective

of this study was to isolate, identify and characterize probiotic organisms from infant feces and

determine their activity against common pathogens. Twenty two (22) isolates of bacteria from

feces of breast-fed infants were characterized by phenotypic, morphological and biochemical

characteristics to identify them as Bifidobacteria. Antibacterial activity of these isolates against

pathogenic organisms was tested by the agar well diffusion method as well as by the modified

agar diffusion method. Among these, four isolates were randomly chosen for further study. Three

of the isolates, B7, B9 and B11 were identified as Bifidobacteria adolescentis on basis of their

carbohydrate fermentation patterns. B5 could not be identified due to its variable fermentation

patterns. All isolates showed inhibitory activity against a variety of pathogenic test organisms,

with zones of inhibition being between 12.02 to 25.03 mm. The highest and lowest zones of

inhibition were both by Isolate B11 against Escherichia coli (25.03 mm) and Pseudomonas

aeruginosa (12.02mm), respectively. The results of this study suggest that the isolated

indigenous Bifidobacteria can be a source of natural antimicrobial agents with potential

applications in Food or Pharmaceutical industries.

Abstract

This study evaluated the antidiarrheal and the antimicrobial study of the plant, Bauhinia

Acuminata (Fabaceae). The methanolic extract of the plant was used for the study. The study

involved the antidiarrheal (castor oil induced diarrhea, magnesium sulphate induced

enteropooling) tests on the Swiss albino mice and the antimicrobial test which includes diffusion

susceptibility test against seven strains of bacteria amongst which six of them is diarrhea-

causing. The study suggested that methanolic extracts was safe up to 2000mg/kg. The crude

methanolic extract of Bauhinia acuminata showed a marked antidiarrheal activity at dose of 200

mg/kg and 400mg/kg- body weight as compared to the standard antidiarrheal agent Loperamide

(dose:1mg/kg-body weight). The result showed significant (P < 0.01) reduction in animal model

in magnesium sulphate induced enteropooling. In castor oil induced diarrhea, it showed

reduction in dose dependent manner. Anti-diarrheal activity was present in the methanolic

extract (200mg/kg and 400mg/kg) which indicate that the crude drug acted by causing decreased

intestinal motility. Any kind of antimicrobial activity was not shown by the methanolic extract of

leaf of this plant, Bauhinia acuminata.

Abstract

Diabetes mellitus is one of the common metabolic disorders and 2.8% of the population suffers

from this disease throughout the world. It is a chronic disease that requires long-term medical

attention to limit the development of its devastating complications and to manage them when

they do occur. It is a disproportionately expensive disease. Due to lack of organized health care

systems in developing countries like Bangladesh, people with this choronic disease are among

the worst sufferers in the society. Recent WHO and IDF reports show that the incidence of

diabetes is increasing at an epidemic rate specially in developing countries probably due to

rapidly changing life-style, food habit and environmental condition. So far, it is well known that

oral hypoglycemic agents like sulphonylureas, biguanides and thiozolidindiones are still the

major players in the management of Type 2 diabetes. However, most of them are costly and have

lots of side effects. So there is a need for better oral antidiabetic agents. Plants have got a vast

potential to provide source materials for antidiabetic agents. However, a limited number of these

plant species have been studied and validated scientifically. World‟s Ethnobotanical information

about medicinal plants reports that almost 800 plants are used in the control of diabetes mellitus.

There are many other plants which are not still scientifically evaluated but they have “folk

medicine reputation”. Momordica dioica and Couropita guinensis have got folkloric reputation

as anidiabetic plants. Therefore, the aim of our study is to explore the antidiabetic effects of

Momordica dioica fruit extracts and Couropita guinensis leaf extracts in streptozotocin induced

diabetic rats and also try to find out some bioactive compounds of these plants.

Abstract

Acanthus ilicifolius (Family: Acanthaceae) and Clerodendrum inerme (Family: Verbenaceae) are

two widely distributed plants of the Sundarbans mangrove forest. The present study was

performed to evaluate some of the selected bioactivities of these two plants. The extracts of the

plants were evaluated for potential antioxidant, antimicrobial and preliminary cytotoxic

properties, using the DPPH free radical scavenging assay, disc diffusion assay and brine shrimp

lethality bioassay respectively. Among the extracts, the methanol extracts of both species showed

best free radical scavenging activity and the IC50 values were 26.30, 104.71 and 100 µg/ml,

respectively, for A.ilicifolius leaf, stem and C.inerme. The chloroform extract of C.inerme

showed maximum activity against gram positive Staphylococcus epidermis with zone of

inhibition 26 mm for 1000 µg/disc. A.ilicifolius leaf chloroform extract showed activity against

S. epidermis and Salmonella typhi. Chloroformic extract of A.ilicifolius stem showed activity

against S. epidermis and Vibrio cholerae while methanolic extract showed activity against

V.cholerae. Chloroformic extract of C. inerme showed activity against Escherichia coli, S. typhi

and S. epidermis and methanol extract against S. epidermis. In the cytotoxic assay, chloroformic

extract of C. inerme showed lowest LC50 value of 9.66 µg/ml. The petroleum ether extract of C.

inerme and methanolic stem extract of A.ilicifolius showed potential preliminary cytotoxic

activity as indicated by LC50 values at the concentration of 13.33 µg/ml and 11.5 µg/ml

respectively.

Abstract

Diabetes is a globally prevalent endocrine disorder. The Psidium guajava has been shown to

possess antidiabetic activity. In our study, we aimed at discovering the underlying mechanism of

its antidiabetic action. The study was carried out in accordance to recommendations of the

international Association for the study of Pain. To evaluate the ability of Psidium guajava in

lowering acute glucose load and basal glucose, we carried out the “Glucose tolerance test”,

“Fasting Blood Glucose” respectively. The effect of sucrose absorption from various segments of

the gut (the stomach, the upper 20 cm, middle, and lower 20 cm of the small intestine, the

cecum, and the large intestine.) was determined by “Six Segment Test”. An “Intestinal

Perfusion” technique was used to study the effect of Psidium guajava on intestinal absorption of

glucose in 36 h fasted non-diabetic rats. Finally alteration of “GUT motility” was determined to

see how long the food content would be in the intestines for sugar in food to be absorbed. Groups

of data were compared using unpaired Student‟s t test and Mann–Whitney U test where

appropriate. Where data were collected over a number of time-points, analysis was based on

repeated measures ANOVA, with Bonferroni adjustment. . One-way ANOVA was performed

and pair-wise comparisons to the control group made using Dunnett‟s test. Differences were

considered significant at P<0·05. Administration of Psidium guajava (0·5 g/kg body weight) to

normal and type 2 diabetic rats did not improve oral glucose tolerance significantly (P=0.08).

Basal blood glucose remained unchanged. Total remaining unabsorbed sucrose in the

gastrointestinal tract of non-diabetic and type 2 diabetic rats, following oral sucrose loading (2·5

g/kg body weight) was significantly (P<0.05) increased by Psidium guajava extract (0·5 g/kg

body weight). However, the extract did not suppress the intestinal glucose absorption. The

extract did not cause significant increase in the gastrointestinal motility. The present findings

indicate that the Psidium guajava probably exerts its hypoglycemic effects through inhibition of

sucrose digestion, not by inhibition of glucose absorption. Currently, we are conducting separate

study on the effects of Psidium guajava on intestinal disaccharidase enzyme.

till date. The objective of the study was to evaluate acute toxicity produced and to calculate

median lethal dose (LD50) of methanol extract of dried ripe fruits of Neoalsomitra clavigera

(Wall) Hutch. (Cucurbitaceae) in Wistar albino rats. This study was carried out according to

Organization for Economic Co-operation and Development (OECD). The powdered drug was

exposed to soxhlet extraction with methanol under control conditions of temperature. The

animals were divided in to five groups (5 animals each group), the one group, out of five was

treated as control group and the remaining four were treated as extract treated group and treated

with 5, 50, 300 and 2000 mg/k.g body weight respectively. From first day of dosing, the animals

were observed for physical changes, routine habit toxic effects and mortality up to 15 days. On

15th, the animals were sacrificed under excessive ether anesthesia and total blood was collected

by puncturing posterior vena cava for serum biochemistry studies and organs like heart, liver,

stomach, kidneys, spleen, and adrenal glands were dissected and exposed to histological studies.

After statistical analysis, all the significant values were compared with control group.

Simultaneously the LD50 value was calculated. The results of serum biochemical studies showed

significant changes after going above to certain dose level and histopathological studies also

showed significant differences. On the basis of these results the lethal dose was also calculated.

On the basis of above study it is concluded that the drug is very lethal at very low doses.

Abstract

Jaundice and allergy are most common diseases among Bangladeshi population. The disease is

widely also prevalent in both urban and rural regions in the country. In rural areas, these diseases

sometimes lead to life-threatening critical situations. Different allopathic drugs were used to treat

them, but play a little role in the managemnet of chronic illness. So the predominantly rural

population of the Bangladesh usually relies on folk medicinal practitioners (Kavirajes) for

treatment of this affliction. In this study, semi-structured questionnaire was employed to conduct

surveys among folk medicinal practitioners of the different villages in Tangail district,

Bangladesh. Informed consent was obtained from the practitioners prior to interviews. It was

observed that the Kavirajes of the selected areas used a total of 16 plants distributed into 10

families for treatment of jaundice ailments. The Rutaceae family provided the largest number of

species (3) and most of the families were contributed single plant. On the other hand of 10 plants

weere distributed into 9 families for treatment of allergy ailments. The various plant parts were

used to treat jaundice and allergy included whole plant, leaves, barks, roots, flowers and, fruits.

The survey highlights the considerable differences in medicinal plant usage by Kavirajes of

different villeges of tangail district. As such, these medicinal plants used by the Kavirajes need

to be scientifically studied in a more rigorous manner, and efforts should be made to collect

information from other Kavirajes in other district of Bangladesh for medication of such disease,

which comprises of a number of ailments prevalent worldwide and suggests that considerable

potential exists for modern scientific studies to be carried out on the medicinal plant species in

the quest for better drugs.

used to evaluate some of these usages. Primary objective of this study is to investigate possible

thrombolytic and Membrane Stabilizing activities of Averrohoa bilimbi. In vitro method was

used for this study using human red blood cells collected from healthy volunteers. Dried powder

of the plant was extracted with methanol and the concentrated methanolic extract was

fractionated by the modified Kupchan partitioning method to provide pet-ether, ethyl acetate,

chloroform and aqueous soluble fractions which were used for both tests. Streptokinase was used

as standard in thrombolytic test whereas acetyl salicylic acid was for membrane stabilizing test.

All fractions revealed significant thrombolytic activity when compared to control (distilled

water) and standard (streptokinase). However, ethyl acetate fraction showed maximum

thrombolytic activity with a value of 28.65% (P<0.01) lysis of blood cells while standard

streptokinase exhibited 49.08% (P<0.001) lysis of clot. All fractions inhibited heat as well as

hypotonic solution induced hemolysis of RBC in vitro. The methanolic extract inhibited 20.76%

(P<0.001) and 37.71% (P<0.001) hemolysis of RBC caused by heat and hypotonic solution,

while compared to 34.49% (P<0.001) and 77.52% (P<0.001) inhibition of hemolysis caused by

standard acetyl salicylic acid, respectively. This plant may be a potential source of thrombolytic

and membrane stabilizing principles.

Abstract

In this study, two Mangrove climber Caesalpinia crista and Cynometra ramiflora from the same

family (leguminosae) were selected based on their traditional uses. In order to find out the

scientific background of such uses, the present study was performed to study some of the

bioactivities (antioxidant, preliminary cytotoxicity and antimicrobial activity) of these plants.

Medium polar solvent (chloroform) extract and polar solvent (methanol) extract of two plants

were taken for the study. In vitro antioxidant potential was evaluated by DPPH free radical

scavenging and ferric chloride reducing power assay. Preliminary cytotoxicity and antimicrobial

activity were conducted by using brine shrimp lethality and disc diffusion bioassay respectively.

Methanolic extract of C.ramiflora (stem) obtained higher free radical scavenging activity

(IC50:21.677µg/ml) and also had a capability to reduce Fe3+

to Fe2+

with reduction activity ranged

(82.697% – 245.454%). Methanolic extract of C.crista showed moderate results in both

antioxidant assays. In preliminary cytotoxic assay, methanolic extract of C.ramiflora and

C.crista were found to show potential activity and LC50 values of both plants were same

(~4µg/ml). Chloroformic extracts of C. ramiflora(leaf and stem) showed best antimicrobial

activity against Bacillus megaterium and Salmonella typhi. Chloroformic and methanolic

extracts of C.crista showed significant activity against Streptococcus aureus and Staphylococcus

epidermis respectively. This research signifies that the plant extracts which have significant

antioxidant property may show cytotoxicity.

Abstract

Traditional medicines derived from medicinal plants are used by about 60% of the world‟s

population. Various types of macroscopic, microscopic, physical, chemical and microbiological

analyses are recommended for quality control of herbal medicines by several regulatory

authorities. Adhatoda vasica L. contains vasicine which acts as a. The present study reveals an

improved method for the identification and quantification of vasicine from Adhatoda vasica L.

Alkaloid vasicine and vasicinone were identified and isolated from the methanolic extract of the

herb followed by column chromatography with Rf values of 0.31 and 0.78 respectively. In HPLC

the phytomarker vasicine exhibited 7.4 min retention time (RT) with mobile phase methanol :

water in a ratio of 40: 60 with flow rate of 0.5ml/min. The compound vasicine was ascertained

with spectral analysis FTIR and LC-MS/MS. Similarly the phytomarker vasicinone was also

identified and ascertained with spectral analysis. The retention time of vasicinone was 10.6 min

with same mobile system and flow rate. Five market preparations containing Adhatoda vasica L.

were collected and subjected for analysis. Specific amount of the liquid preparation was taken

from each and ten times diluted with distilled water. The solution was acidified by 1% citric acid

solution. The acidified solution was then basified with ammonia (25% solution) followed by

extraction with chloroform. The organic layer was separated and evaporated to dryness. Dried

organic fraction was then ten times diluted with methanol and analyzed by HPLC with a solvent

system containing methanol: water in a ratio of 40: 60 with flow rate of 0.5ml/min. The RT of

major peak was found at 7.4 min, which confirmed the presence of vasicine in market

preparations. The identification and quantitation of phytomarker vasicine in the market

preparations was confirmed by comparing its retention time and peak area with standard vasicine

(Germany). The amount of vasicine in five different market preparations of sample-1, sample-2,

sample-3, sample-4 and sample -5 were determined by using a standard calibration curve of

vasicine from concentration range 75 to 300 μg/ml (R2=0.982). The five commercial products

contained vasicine 3.83g, 1.76g, 2.17g, 3.13g and 1.08g in 100mL preparation respectively.

Abstract

Ranunculus sceleratus Linn. belonging to the family of Ranunculaceae is an annual plant, native

to North America, Eurasia, and Asia, where it grows especially in wet and moist habitat. The aim

of the present study was to identify polyphenols through high performance lipid chromatography

(HPLC) profiling analysis. Ethanol extract of the aerial parts of R. sceleratus was prepared

through hot extraction technique using Soxhlet extractor. HPLC technique was utilized to get

chromatographic profile of the polyphenols present in the extract. HPLC profile of the extract

was compared with the profile of the standard polyphenols. Polyphenols were identified by

comparing the retention time of the compounds with the standards. Gallic acid, catechin, caffeic

acid, vanillic acid, epicatechin, para-coumaric acid, rutin hydrate, ellagic acid, and quercetin

hydrate were used as standard polyphenols. Caffeic acid, rutin hydrate, and quercetin hydrate

were identified in the ethanol extract as compared with the HPLC profile of the standards.

Retention time of these three polyphenols was 16, 21, and 25 min, respectively. HPLC profile

analysis clearly demonstrated that the aerial part of R. sceleratus contains some polyphenols.

Abstract

In one of the Ayurvedic text it is mentioned that the root powder of the plant is administered in

case of leucorrhoea and Candida albicans, yeast like fungal stain is generally responsible for this

pathological leucorrhoea. By taking consideration of these points, the present study was carried

out. This study was undertaken to know antifungal effect of methanolic extract of root of

I.sepiaria against the fungal strain Candida albicans and HPTLC analysis also carried out. The

whole plant of I. sepiaria was collected from the campus of Gujarat Ayurved University. The

collected samples were authenticated by the Botanical Survey of India, Office of the Scientist-

„F‟, Central National Herbarium, Botanic Garden, Howrah, West Bengal, specimen No.-

CNH/104/2011/Tech.II/581. The roots were collected and extracted with methanol to assessed

antifungal activity by agar well diffusion method. The different solvent extracts were subjected

for chromatographical separation and confirmation of chemical compounds by using various

solvents and spraying reagents under visible and UV light of long and short wavelengths by

following standard procedures. The result shows that the root of I. sepiaria is having phyto-

constituents like alkaloids, carbohydrates, glycosides, phenolic compounds etc and HPTLC study

of the different extract showed the presence of spots at different Rf values. The methanolic

extract of root was found to possess significant antifungal activity. The methanolic extract of

root of I. sepiaria is having very good antifungal activity and this supports the use of root in the

treatment of leucorrhoea. Further researches are needed to explore the phyto constituents

particularly responsible for the observed activity profile.

Abstract

The amount of phenolics, flavonoids, anthocyanins in ethanol extracts and antioxidant activity of

both ethanol and lipophilic extracts of common fruity vegetables in Bangladesh were studied.

Among the ethanol extracts of 15 fruity vegetables, M. oleifera had highest total polyphenol

content (85.05 mg gallic acid equivalent (GAE)/g extract) followed by L. acutangula (61.74 mg

GAE/g extract) and A. esculentus (48.92 mg GAE/g extract). L. acutangula had high content of

flavonoids (14.46 mg (+)-catechin equivalent (CE)/g extract), which was almost similar to L.

siceraria (13.67 mg CE/g extract) followed by A. esculentus (11.95 mg CE/g extract) and S.

melongena (11.42 mg CE/g extract). Highest anthocyanins content was in F. hispida (2.22

μmol/g extract) followed by S. melongena (1.04 μmol/g extract). Ethanol extracts of A.

esculentus, F. hispida, L. acutangula, L. siceraria and S. melongena exhibited high DPPH free

radical scavenging activity with IC50 of 70.4, 64.9, 70.4, 64.9 and 94.3 μg/mL respectively,

whereas for the same lipophilic extracts of F. hispida and S. melongena showed lowest (37

μg/mL) IC50 followed by M. oleifera (47.6 μg/mL), L. siceraria (57.5 μg/mL) and A. esculentus

(63.3 μg/mL). These vegetables also showed high reducing powers, NO scavenging and total

antioxidant capacity. Therefore, the top five potential fruity vegetables consist of both

hydrophilic and lipophilic antioxidant(s), the order being F. hispida > M. oleifera > A.

esculentus, L. acutangula > L. siceraria > and S. melongena.

Abstract

From ancient time man has been using plants as a potential mean of ailment for their various

sorts of disease. The healing properties of certain plants were identified, noted and conveyed to

the successive generations. We can see the ample evidences in many written documents

preserved monument that contain ethnomedicinal use of different medicinal plants e.g.

Ayurveda. Still man is searching for new source of natural products in plants for designing more

effective drugs. The following study is based on the ethnomedicinal use of herbs of the

Sundarbans mangrove forest. The entire study includes twenty four herbs of the Sundarbans

mangrove forest while 6 plants have been reported to be vital depending on the number of

compounds isolated and traditional medicinal uses. The plants are Caesalpinia crista, Derris

trifoliate, Portulaca oleracea, Cassia tora, Acalphya indica , Euphorbia hirta. The objective of

the study is to investigate the potential of these plants to be used as novel sources of drug and to

inform the latest progress to the researchers for further work on these plants as a promising

alternative.

Abstract

Medicinal plants, besides having therapeutic values against diabetes mellitus may have other

pharmacological actions. To compare antibacterial activity of antidiabetic plants in Bangladesh,

methanol extracts of them were tested against six pathogenic bacteria. Among the extracts,

Coccinia indica (leaves), Gymnema sylvestre (Bark), Swertia chirata (whole part) and Syzygium

cumini (seed) showed strong inhibition against Salmonella typhi, S. paratyphi A, Staphylococcus

aureus and Shigella dysenteriae in disc diffusion test at the concentration of 400 μg/disc. No

extract inhibited the growth of Vibrio cholerae. The lowest IC50 value (5.47 mg/mL) was found

in C. indica against S. paratyphi A. Since, C. indica, G. sylvestre, S. chirata and S. cumini were

found potential, they had been fractionated into five fractions namely hexane, diethylether,

chloroform, ethylacetate and methanol. Among the fractions, methanol fraction of S. cumini

potentially inhibited the growth of all four bacteria at the concentration of 400 μg/disc, whereas,

S. paratyphi A was inhibited by C. indica and S. typhi by both G. sylvestre and S. chirata.

However, the methanol fractions showed lesser inhibition than that of methanol extracts against

the bacteria which entails the idea of synergistic action. Since, methanol fractions of the four

plants were the most potent, their IC50, MIC and MBC values were determined. Altogether,

among the common antidiabetic plants, S. cumini had potent antidiabetic activity that might be

used in treating both diabetes and bacterial infections.

Abstract

Wattakaka volubilis is widely used in Indian traditional medicine to treat pain, cough, fever,

dyspepsia and diabetes. The aim of the study was to evaluate antidiabetic properties of extract of

W. volubilis. The present study investigated the protective effect of W. volubilis leaf extract

against Streptozotocin (STZ) induced diabetes in rats. The petroleum ether cold macerated

extract (PEME) of W. volubilis was evaluated to quantify lupeol by HPTLC method. Male

Wistar rats were divided into five groups (with six rats each) and fed at libitum: the control

(0.9% saline), STZ treated rats with or without supplementary PEME of W. volubilis and

metformin (50, 100 and 250 mg/kg body weight) for three weeks. The blood-glucose, α-amylase,

alanine transaminase (ALT), alkaline phosphatase (ALP) and bilirubin levels were measured on

7, 14 and 21-day of PEME treatment on STZ treated rats. Antioxidant properties were assessed

by estimating hepatic catalase and lipid peroxidation. Histopathological changes in the liver were

examined with hematoxylin-eosin staining. Morphological changes in the liver were also

examined with glutaraldehyde fixation. The PEME had 382.82 μg of lupeol, treatment of PEME

in experimental rats by oral injections for 21 days showed reductions in the levels of serum

biochemical markers. PEME treatment also significantly recovered catalase and decreased lipid

peroxidation towards normal. Histopathology and scanning electron microscopy results showed

that PEME administration suppressed the abnormal liver cellular degenerations in STZ treated

rats. These results suggest that PEME has a protective effect over STZ-induced diabetes.

Abstract

Diabetes is a widely prevalent endocrine disorder worldwide. The Beta vulgaris has been shown

to possess antidiabetic activity. Here we aimed at elucidating the underlying mechanism of its

antidiabetic action. The study was carried out in accordance to recommendations of the

international Association for the study of Pain. To evaluate the ability of Beta vulgaris to lower

acute glucose load and basal glucose, we carried out the “Glucose tolerance test”, “Fasting Blood

Glucose” respectively. The effect of sucrose absorption from various segments of the gut (the

stomach, the upper 20 cm, middle, and lower 20 cm of the small intestine, the cecum, and the

large intestine.) was determined by “Six Segment Test”. An “Intestinal Perfusion” technique was

used to study the effect of Beta vulgaris on intestinal absorption of glucose in 36 h fasted non-

diabetic rats. Finally, alteration of “GUT motility” was determined to see the time food content

would be in the intestines for sugar in food to be absorbed. Groups of data were compared using

unpaired Student‟s t test and Mann–Whitney U test where appropriate. Where data were

collected over a number of time-points, analysis was based on repeated measures ANOVA, with

Bonferroni adjustment. . One-way ANOVA was performed and pair-wise comparisons to the

control group made using Dunnett‟s test. Differences were considered significant at P<0·05.

Administration of Beta vulgaris (0·5 g/kg body weight) to normal and type 2 diabetic rats

significantly (P<0.01) improved oral glucose tolerance. It also significantly lowered the basal

glucose in the test subjects. It did not significantly change the total remaining unabsorbed

sucrose in the gastrointestinal tract of non-diabetic and type 2 diabetic rats, following oral

sucrose loading (2·5 g/kg body weight). Beta vulgaris did not significantly suppress the intestinal

glucose absorption in both non-diabetic and type 2 diabetic rats. However, the extract

significantly (P<0.01) increased the gastrointestinal motility of both type 2 diabetic and non-

diabetic rats. The present findings indicate that the Beta vulgaris does not exert its hypoglycemic

effects by inhibition of absorption, rather, probably, through enhancing insulin secretion or

sensitivity.

Abstract

The quality control parameter of herbal medicine has become an important safety concern

worldwide. The regulatory authorities of the developed countries emphasize the establishment of

the quality parameters as prerequisite for patient safety. Traditionally herbal medicines are

practiced in our country. But there are no specific quality parameter established or practiced in

our country. As an inception a reversed phase high performance liquid chromatography method

has been developed for the estimation of gallic acid in herbal preparations containing the fruits of

Phyllanthus emblica, Terminalia chebula and Terminalia bellirica. For doing this at first the

amount of gallic acid in the three fruits has been determined and later the amount of gallic acid

found in the market preparations (Triphala and Amlaki Rasayan) are compared with these. A

C18 column (250mm × 4.6 mm i.d., 5 µ particle size) was used with mobile phase composed of

acetronitrile : acetic acid (0.1 %) in a ratio of 20 : 80 at a flow rate of 1 mlmin-1

. The UV

detection was performed at 272 nm and the retention time of gallic acid was found 3.8 min

(approx). According to the result the highest amount of gallic acid was observed in Terminalia

bellirica ( 2.22 to 2.34%) and the lowest amount was found in Terminalia chebula (1.44 to 1.54

%). Most of the market preparations showed significant variation in gallic acid content. This

analytical approach can be used as a quality control tool in all kinds of herbal medicine

manufacturing industry for ensuring the quality of plant raw materials and the finished product as

a routine practice.

Abstract

Researchers showed their interest to uncover the mystery of sundarban plants that can survive on

harsh environment years after years. Based on the historical success of natural products as

valuable drugs and the urgent need for new drugs, a number of the Sundarbans mangrove

medicinal plants have been evaluated for their pharmacological properties. This effort has been

set out to compile and appraise the results on bioactive properties of Sundarban mangrove trees

based on ethnobotanical uses and also summarize the bioactive compounds identified from

mangrove trees. About 27 trees have been selected due to their ample uses in different diseases.

From different literature searches, it has been found that 5 trees named Barringtonia racemosa,

Pongamia pinnata,Crataeva religiosa, Pandanus tectorius and Ficus sp.are mostly used by the

local people of the Sundarbans area. These trees possess novel compounds like bartogenic acid,

pongapinnol, lupeol, stigmasterol and serrat-3-one etc. Due to the rising incidence of resistance

to synthetic antibiotics and in light of the rising costs of medicines, the research proponents of

this study aims to discover most efficient drugs with the end view of providing low cost of

medications and the prevention of resistance.

Abstract

Snake bite is a result of an unfortunate accidental interaction between a snake and a human victim. It

is the single most important toxin-related injury, causing substantial mortality in many parts of the

Africa, Asia, and the Americas. A World Health Organization-funded study estimated about 8,000

cases of snakebite with over 20% mortality in Bangladesh annually. A medically important land

snake in Bangladesh includes the krait, cobras, and vipers. Medically important snake species are the

ones that fall into one of the three categories: bite usually causes death or disability. Snake venom is

highly modified saliva (Reptile Venom Research that is produced by special glands) of certain

species of snakes. The glands which secrete the zootoxin are a modification of the parotid salivary

gland of other vertebrates, and are usually situated on each side of the head below and behind the

eye, encapsulated in a muscular sheath. The glands have large alveoli in which venom is stored

before being conveyed by a duct to the base of channeled or ubular fangs, through which it is ejected.

Snake venom consists of proteins, enzymes, substances with cytotoxic effects, neurotoxins,

coagulants and anti-coagulants. The objective of this study was to conduct a survey amongst the local

specialists in the Barandra ( Rajshahi & Rangpur division) and Shamatat (Khulna and Part of Barisal

Divission) region of Bangladesh, to collect information on plants used to treat snake bite. Local Folk

Medicinal Practitioners of the study area were selected randomly and interviewed with the help of

translators to gather information on the knowledge and use of plants used as a remedy for snake bite.

In-depth information regarding plants type, preparation of medicines, ailments for which they are

used, dosages, and side effects if any, were obtained from the local specialists. All plants were

photographed, collected, identified, and vouchers were stored at the Bangladesh National Herbarium.

Information on twenty plants was obtained. The collected information indicates that the following

plants are used against snake venom: Justicia adhatoda L., Sansevieria trifasciata, Agaricus

albolutescens, Rauwolfia canescens L., Rauwolfia serpentine (L.) Benth ex Kurz, Eclipta prostrate

L. Emilica sonchifolia (L.), Anogeissus latiofolia, Cajanus cajan (L.), Clitoria ternatea L.,

Couroupita guianensis, Leucas aspera (Wild.), Anisomeles malabarica (L.), Wissadula periplocifolia

(L.), Ceropia peltata L., Piper longum L., Morinda citrifolia L., Solanum torvum Swartz, Curcuma

longa L. These medicinal plants, because of their long history of usage present considerable potential

for isolation of components, which can lead to discovery of efficacious anti-venom drugs.

Aegiceras corniculatum, Brownlowia tersa, Clerodendrum inerme and Dalbergia spinosa which

show most ethnobotanical prospects among all the shrubby mangrove plants of the Sundarbans.

Most of them have antinociceptive, antidiarrhoeal analgesic, anthelmintic, anti-inflammatory,

antimicrobial, antipyretic, anti-spermicidal, anti-ulcerogenic, aphrodisiac, astringent, antioxidant

and larvicidal etc bioactivities. Different groups of compounds including flavonoids, steroids,

alkaloids, glycosides, quinones and phenolic compounds are isolated from these mangrove

plants. Moreover, this report is a compilation of information regarding traditional uses,

biological activity and isolated bioactive compound obtained from data of previous assessments.

Abstract

This research work has been carried out to detect the presence of and if present, to quantify

caffeine, preservatives and antioxidants in dairy products using reversed phase High

Performance Liquid Chromatography (HPLC) method. Three different analytical methods were

used to evaluate the content of caffeine, five preservatives namely benzoic acid, methyl paraben,

propyl paraben, butyl paraben and formaldehyde, and two antioxidants namely Butylated

Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT). The evaluation of caffeine,

benzoic acid, propyl paraben, butyl paraben, BHA and BHT was performed using a C18 column

(150 mm × 4.6 mm internal diameter, 5 μm particle size) with a gradient flow rate of acetonitrile

and acidic solution of sulfuric acid of pH 2.3 from ratio (%v/v) of 15:85 to 80:20 at a flow rate of

2.0 mL/min and detecting wavelength of 265 nm. The retention times of caffeine, benzoic acid,

propyl paraben, butyl paraben, BHA and BHT were about 3.6, 11.6, 13.0, 13.3, 13.6 and 16.7

minutes respectively. For the evaluation of methyl paraben, the same C18 column was used with

acetonitrile and acidic solution of sulfuric acid of pH 2.3 at a ratio (%v/v) of 18:82 as mobile

phase and detection was performed at wavelength of 254 nm using flow rate of 2.0 mL/min. The

retention time of methyl paraben was 6.8 minutes. Formaldehyde was evaluated with a pre-

column derivatization with 2,4-dinitrophenylhydrazine. The derivative was then analyzed using

another C18 column (250 mm × 4.6 mm internal diameter, 5 μm particle size) with acetonitrile

and water at a ratio (%v/v) of 45:55 as mobile phase and detected at the wavelength of 345 nm.

The retention time of formaldehyde was 15.8 minutes. 41 marketed dairy products of home and

abroad were collected from Dhaka, Bangladesh in 2013, and then investigated. None of those

products was found to be labeled to contain any of benzoic acid, methyl paraben, propyl paraben,

butyl paraben, formaldehyde, BHA or BHT. Caffeine was not also labeled but six chocolate milk

products were labeled to contain cocoa powder which may be the source of caffeine. 17.1% of

the products were exhibited benzoic acid positive. Among these, only 14.3% of the benzoic acid

positive products were approved by the Joint FAO/WHO Expert Committee on Food Additives

(JECFA). 14.6% of the products showed positive response to caffeine and all were below the

tolerance limit (<200 ppm) set by FDA. None of the dairy products were found to contain methyl

paraben, propyl paraben, butyl paraben, formaldehyde, BHA and BHT. The amount of the total

benzoic acid and caffeine were between 41 ~ 6104 ppm and 5 ~ 13 ppm respectively.

Abstract

A precise, sensitive and versatile reversed-phase HPLC method was developed that allowed the

separation and simultaneous determination of caffeine, benzoic acid, methyl paraben, propyl

paraben, butyl paraben, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT).

The separations were achieved by using a gradient flow rate of acetonitrile and acidic solution of

sulfuric acid (pH 2.3) from ratio (% v/v) of 15:85 to 85:15. A Capcell Pak analytical C18 column

(150 mm×4.6 mm, 5 μm particle size) at a flow rate of 2.0 mL/min was used and detecting

wavelength was 265 nm. Under these conditions, separation of these components were achieved

in less than 18 min where analytical characteristic like linearity (Caffeine: 40-200 ppm; R2=

0.992 and Benzoic acid: 50-400 ppm; R2= 0.995) was evaluated. The developed method was

applied to analyze 60 marketed food and beverage products (mainly domestic), comprising

energy drinks (21), soft drinks (34) and malt beverages (5). The results showed 53.33% of

marketed products were found to contain caffeine, among these 15.6% of caffeine containing

products exceeded the tolerance limit of caffeine (> 200 ppm) set by the United States Food and

Drug Administration (US FDA). Benzoic acid was found in 65% of marketed products; among

these 10.3% of benzoic acid containing products exceeded the maximum allowable limit of

benzoic acid (> 600 ppm) set by Joint FAO/WHO Expert Committee on Food Additives

(JECFA).
