EVALUATION OF ANTIOXIDANT PROPERTY OF SEEDS OF Pongamia pinnata BY DPPH METHOD(2,2-diphenyl-1-picrylhydrazyl)

Pongamia pinnata is commonly known as Karanj and Indian beech in English. The metabolites present in this plant mainly are from the class of flavonoids and oils. It also serves as a source of biodiesel. Many parts of this plant have great medicinal value like leaf and flower and possess the antioxidant activity as reported. The aim of this study was to investigate and analyse its antioxidant properties of the principle secondary metabolite extracted from the seeds of plant. The antioxidant property was analysed by DPPH assay using n-hexane, DCM, ethyl acetate fraction and with the purified compound. The results of our study shows that the ethyl acetate fration of plant seeds possesses significant antioxidant activity having IC50 values 42.51 μg/ml which indicates that the products from this plant could be very much helpful for slowing down or preventing diseases which are induced by oxidative stress.
