PHYTOCHEMISTRYIt is the study of phytochemicals.Phytochemicals are chemicals obtained from

plants.Also called as secondary metabolic

compounds.Eg: saponins,alkaloids,volatile oils,flavonoids

etc.

PHYTOCHEMISTRYGeneral techniques used to derive these

phytochemicals are:Thin layer chromatographyColoumn chromatographyGas chromatographyHPLCMass spectrometryNuclear magnetic resonance

MEDICINAL PLANTS

MEDICINAL PLANTSPlants having medicinal properties is known

as medicinal plants.These plants synthesises substances that are

useful to the maintenance of health in humans.

These include aromatic compounds such as phenols or tannins.

Many are secondary metabolites.

SIGNIFICANCE OF MEDICINAL PLANTSMany modern medicine are produced

indirectly from medicinal plants.eg, aspirin.Plants are directly used as medicine all over

the world.for eg. Chinese medicine,Indian medicine.

Medicinal plants are resource of new drugs.Cultivation and preservation of medicinal

plants protect biological diversity,for eg, metabolic engineering of plants.

METHODOLOGYDifferent techniques involved in the study of

phytochemicals are:ExtractionIsolationStructural elucidationChromatography techniques.

EXTRACTIONExtraction of a phytochemical include

following steps-Homogenisation

Extraction

Concentration

ISOLATION AND STRUCTURAL ELUCIDATIONIsolation of compounds is done by gradient

solvent fractionation.

Then structural elucidation of these compounds is done by 1D or 2D NMR.

RESEARCH WORKON TULSI(OCIMUM SANCTUM)

Antidiabetic Indian Plants: a Good Source of Potent Amylase Inhibitors.

Bhat M, Zinjarde SS, Bhargava SY, Kumar AR, Joshi BN.Institute of Bioinformatics and Biotechnology, University of

Pune .The chloroform, methanol and aqueous extracts were

prepared from the leaves the plant. It was observed that chloroform extracts have significant

alpha amylase inhibitory property.

RESEARCH WORKSeveral research on tulsi have proved it to be a

remedy for several common ailments such as.1. Healing Power2. Fever & Common Cold3. Sore Throat4. Respiratory Disorder5. Kidney Stone6. Heart Disorder7. Stress

SIGNIFICANCE OF PHYTOCHEMISTRYStudy of several phytochemicals can help in

improving the efficacy of drugs.Several studies is in progress to cure

diseases like cancer,arthritis,diabetes etc
