Abstract
Legume is a major source of antioxidant and nutritional component that is very helpful for human health. In recent years, the functional properties of legume seed have received attention, particularly with respect to antioxidant, antitumor, anti-diabetic and anti-cholesterol effects. The objective of this study was to investigate the phenolic compound, flavonoid, antioxidant capacity and nutritional profiles of five legume seeds. The phenolic content determined according to the Folin Ciocalteu method, for five legume samples varied from 13.68 to 35.5 mg Tannic acid equivalent/g of extract. Flavonoid content was measured using 2% aluminum chloride varied from 1.21 to 4.81 mg quercetin equivalent/g of extract. Red bean contained maximum phenolic (35.5 mg/g extract) and flavonoid (4.81 mg/g extract) content that was statistically different from other legume seed (p<0.05). Antioxidant activities were comparatively assessed by ABTS (2, 2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) and DPPH (2,2-diphenyl-1- picrylhydrazyl) free radical decolorization assay method. Red bean, soybean and black bean showed good free radical scavenging capacity by ABTS and DPPH.
