| Abstract: | Ethanolic extract of Canthium parviflorum Lam. leaves 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  g/ml showed maximum scavenging activity (51.60%) of ABTS radical cation followed by the iron chelation (45.12%) at the same concentration. However, the extract showed only moderate hydroxyl radical scavenging activity (6.42%). Total antioxidant capacity was found to be 12.9 mg ascorbic acid equivalents at 500 g/ml extract concentration. There was a positive correlation between the total phenolic content and antioxidant capacity, R2 = 0.8313, whereas the correlation between the total flavonoids and antioxidant capacity was determined to be R2 = 0.8102. The results suggest that phenolics and flavonoids in the leaves provide considerable antioxidant activity. |
