Total phenolic content and in vitro antioxidant activity of Vigna sinensis. pp. 1393-1400. ISSN 2231-7546
Abstract
Vigna sinensis also known as long-podded cowpea or Chinese long bean (Family:Fabaceae) is most widely grown in Southeast Asia. They are a good source of protein vitamin A vitamin C iron phosphorus and potassium. The antioxidant potential of crude methanol extract chloroform and ethyl acetate soluble fractions of Vigna sinensiswas screened for in- vitro antioxidant activity using total phenolic content ferric reducing power 2 2-azinobis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assay ferric thiocyanate (FTC) and thiobarbituric acid (TBA) tests. It was found that ethyl acetate fraction have maximum amount of polyphenolics compounds (2.69 mg/g GAE in concentration 0.5 mg/mL); more effective than methanol and chloroform extract.This fraction also exhibited fairly good antioxidant activity with in both TBA (17.39 mg/g GAE) and FTC (12.65 mg/g GAE) methods.
