title: Free radical scavenging activity of the alcoholic extract of Trewia polycarpa roots in arthritic rats.
abstract: The alcoholic extract of Trewia polycarpa roots (TPE), which exhibited significant anti-inflammatory activity, was evaluated for the possible mode of action by studying its antioxidant potential in adjuvant-induced arthritic rats. The biological defence system constituting the superoxide dismutase, glutathione peroxidase, ascorbic acid showed a significant increase while the lipid peroxide content was found to decrease to a large extent on TPE treatment thereby indicating the extracts free radical scavenging property. Histopathological studies too supported anti-arthritic potential of the roots of Trewia polycarpa.
