In Vitro Antioxidant Activity

The total phenolics, flavonoids and in vitro antioxidant activity of petroleum ether, benzene, ethyl acetate, methanol and ethanol extracts of stem of Drypetes sepiaria were determined using various antioxidant model systems viz, DPPH, hydroxyl, superoxide, ABTS and reducing power. Total phenolic content was estimated by Folin-Ciocalteau method. Flavonoids were determined by Aluminium chloride method. The total phenolics and flavonoids contents were found to be 0.81 g 100 g-1 and 1.12g 100 g-1 respectively in the methanol extract. Among the solvent tested, methanol and ethanol extracts of D. sepiaria stem showed potent in vitro antioxidant activities. This investigation explored that D. sepiaria stem is a potential source of natural antioxidant.
