In vitro antioxidant activity in ethanolic leaf extract of Tabernaemontana divaricata (L.).

Abstract

Present study is focussed to analyze in vitro antioxidant activity in leaf of Tabernaemontana divaricata (L.). In this study different concentrations of ethanolic leaf extract (200, 400, 600, 800 and 1000µg/ml) are used to perform various assays (DPPH radical scavenging, Superoxide anion radical scavenging, Nitric oxide scavenging and hydrogen peroxide scavenging) for the determination of antioxidant potential in leaves. Concentration based scavenging activity was observed in all assays. From these results, this study expose that the leaf have the ability to act against free radicals.
