| Abstract | The genus Hypericum is a large genus of herbs or shrubs with more than 450 species dispersed worldwide. The plants grow generally in temperate regions and are used in traditional medicine in many parts of the world. In this study, antioxidant activity of petroleum ether, benzene, ethyl acetate, methanol and ethanol extract of bark of Hypericum mysorense was determined. Antioxidant activity was evaluated using four different reactive oxygen species (ROS) scavenging assays containing DPPH (1,1-diphenyl-2pricrylhydrazyl) free radical, hydroxyl radical, superoxide anion, ABTS radical and reducing power assay. Ethanol extract of Hypericum mysorense (800μg/ml) exhibited the maximum DPPH (113.64%) and Superoxide (113.27%) radical scavenging activity. Methanol extracts showed higher Hydroxyl (106.31%) and ABTS (116.22%) radical scavenging activity. It also exhibited higher reducing activity. Hence, these extracts could be considered as natural antioxidants and may be useful for treating diseases arising from oxidative deterioration. KEYWARDS: Hypericum mysorense bark, DPPH, free radical, reducing power. |
