IN VITRO ANTIOXIDANT ACTIVITY OF DRYNARIA QUERCIFOLIA L. RHIZOME
AbstractAntioxidant activity of methanolic extract of Drynaria quercifolia rhizome at different concentrations (100, 200 and 300µg/ml) were studied in various in vitro models. Results were compared with standard ascorbic acid. Antioxidant activity of extract was increased with the increasing concentration. The order of antioxidant potential according to models were found to be highest in nitric oxide scavenging activity followed by total antioxidant activity, reducing power assay and hydrogen peroxide scavenging activity. IC50 values were found to be 180, 230, 230 and 240µg/ml respectively in nitric oxide scavenging activity, total antioxidant assay, reducing power assay, and hydrogen peroxide scavenging activity. In conclusion, the results of present analysis demonstrated that Drynaria quercifolia rhizome possess potential antioxidant activity, and could be used as a viable source of natural antioxidants.
