Abstract
The present study involves the determination of antioxidant activity of the selected extracts of Homonoia Retusa., isolation and characterization of phytoconstituents of the ethanol extract by column chromatography.The antioxidant potential of plant stem extracts were investigated by hydroxyl radical scavenging activity, super oxide free radical scavenging activity, DPPH assay, nitric oxide radical scavenging activity, total antioxidant activity. Among the three extracts ethanol extract was having maximum antioxidentactivity. So the ethanol extract was subjected to column chromatography,by means of gradient elution technique.The fractions 272-306 ,gave the compound B1.Later by spectral analysis they were found to be Coumaric acid-O-glucoside
