V. Sreedhar, L. K. Ravindra Nath, N. Madana Gopal and M. Sanjith Nath

The selected plant extracts and known antioxidant ascorbic acid at various concentrations produced dose dependent inhibition of superoxide radicals, hydroxyl radicals, lipid peroxidation and DPPH radical activities. The IC50 values for superoxide radical with chloroform and methanolic extracts of Vitex quinata were found to be 208.17 µg, 269.32 µg. The IC50 values for hydroxyl radical with chloroform and methanolic extracts of Vitex quinata were found to be 265.32 µg, 312.56 µg. The IC50 values for inhibition of lipid peroxidation activity with chloroform and methanolic extracts of Vitex quinata were found to be 281.23 µg, 336.81 µg. The IC50 values for DPPH radical with chloroform and methanolic extracts of Vitex quinata were found to be 110.12 µg, 154.50 µg.
