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 sinensis was 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.
