Abstract

Objective: Survey antioxidant activities of some familiar legumes in the family Fabaceae.

Materials and methods: Seven types of tree seeds commonly: Vigna unguiculata (L.) Walp. subsp. cylindrica. (L.) Verdc.; Vigna radiata; Vigna angularis; Glycine max; Lablab purpureus; Arachis hypogea; Vigna unguiculata (L.) Walp. subsp. unguiculata. Surveys were done on dry seed of legumes. Total antioxidant activity is measured by two methods DPPH (1,1-diphenyl-2-picrylhydrazyl) and FRAP (Ferric ion Reducing Antioxidant Power), on four segment extracts: DCM extract, EtOAc extract, ethanolic extract, water extract.

Results: Both methods DPPH and FRAP were similar to the survey results. Total antioxidant activity of Vigna angularis is higher than other legumes, ethanolic extracts are the strongest.

Conclusions: Survey results showed that Vigna unguiculata (L.) Walp. subsp. cylindrica. (L.) Verdc.; Vigna angularis; Arachis hypogea have strong antioxidant effects, but result of both methods showed that Vigna angularis is very high.
