Abstract

This study examined the nutrient components and physicochemical properties of Acer termentosum Maxim. leaf as a natural health food source. To accomplish this purpose, the general and antioxidative contents of Acer termentosum Maxim leaf were measured. Total contents of carbohydrates, crude protein, crude lipid, and ash were 53.6%, 24.3%, 3.5%, and 3.5%, respectively. Caloric content of Acer termentosum Maxim was 246.5 kcal, while total dietary fiber was 46.7%. Regarding mineral contents, K was the most abundant mineral, followed by Ca, Mg, and P. Therefore, Acer termentosum Maxim is an alkali material. Total phenol contents of the 70% ethanolic extracts of Acer termentosum Maxim was 116.35ยฑ1.4 mg GAE/g. Total flavonoid contents of the 70% ethanolic extracts were 20.3ยฑ1.23 mg RE/g. The antioxidative activities of Acer termentosum Maxim. were significantly increased in a dose dependent manner on DPPH(1,1-Diphenyl-2-picrylhydrazyl) radical scaveng-ing, ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) radical scavenging, FRAP (ferric reducing antioxidant power) activity, reducing power. It is expected that follow up study of Acer ter-mentosum Maxim through developing processed food and evaluation of their functional properties would pro-vide useful information as a source of functional foods.
