Abstract : Ethanolic extract of leaves of Elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, ABTS+ )2, 2-azinobis-)3-ethylbenzothiazoline-6-sulphonate( radical scavenging and hydroxyl radical scavenging activities. The extract at 500 mg/ml showed maximum Iron chelating activity )76.70percent( followed by the scavenging of the ABTS+radical )55.77percent( at the same concentration. However, the extract showed only moderate hydroxyl radical scavenging activity )13.43percent(. Total antioxidant capacity was found to be 24.18 mg ascorbic acid equivalents at 500 mg/ml extract concentration. There was a positive correlation between the total phenolic content and antioxidant capacity, R2= 0.8547, whereas the correlation between the total flavonoids and antioxidant capacity was determined to be R2=0.8413. The results suggest that phenolics and flavonoids in the leaves provide substantial antioxidant activity.
