The methanolic extract of Sida retusa Linn.(Malvaceae),Urena lobata Linn.(Malvaceae)and Triumfetta rhomboidea Jacq.(Teliaceae) roots were found to inhibit lipid peroxidation, scavenge hydroxyl and superoxide radicals in vitro. The quantity of S .retusa root extract required for 50% inhibition of lipid peroxidation, scavenging hydroxyl radical and superoxide radical was 1130.24 ug/ml respectively. IC 50 of root extract of U.lobata was 470.60 ug/ml, 1627.35ug/ml and 1109.24 ug/ml for superoxide radical scavenging, hydroxyl radical scavenging and lipid peroxidation respectively. T .rhomboidea root extract required for IC 50 was 336.65 ug/ml, 1346.03 ug/ml and 1004.22 ug/ml for superoxide scavenging, hydroxyl radical scavenging and lipid peroxidation respectively. The present investigation indicated that S. retusa, U.lobata and T .rhomboidea possessed significant antioxidant activity. |
