ABSTRACT:
The present study involves the determination of antioxidant activity of aqueous and ethanolic extracts of the plant Pajanelia longifolia (Willd.) K. Schum, isolation and characterization of flavonoid from the ethanolic extract by column chromatography. DPPH assay, ABTS assay, hydroxyl radical scavenging activity, super oxide free radical scavenging activity, nitric oxide radical scavenging activity and total antioxidant activity methods were used to study the antioxidant potential of the whole plant. Among the two extracts, the alcoholic extract shows better antioxidant activity. The alcoholic extract was subjected to column chromatography by gradient elution technique and the fraction 98-102 was found to be 3',4',5,7- tetrahydroxy-3-o- rhamnoglucosyl flavonone.
