OBJECTIVE: Twenty one plants as ingredients of Thai traditional preparation called Sahasthara for relieve muscles pain and distal numbness were studied for their antioxidant and anti-inflammatory activities. MATERIAL AND METHOD: The extracts were obtained by maceration with 95% ethanol. They were tested for their antioxidant activity by DPPH scavenging assay and anti-inflammatory activity by determination of inhibitory activity on lipopolysaccharide (LPS) induced nitric oxide (NO) production in RAW 264.7 cell lines using Griess reagent. RESULTS: The ethanolic extract of Terminalia chebula Retz. (Gall) showed the highest antioxidant activity (EC50 = 3.34 microg/ml). Its fruit extract also exhibited the most potent inhibitory activity on lipopolysaccharide (LPS) induced nitric oxide (NO) production in RAW 264.7 cells, followed by Atractylodes lancea and Baliospermum montanum (IC50 = 3.3, 9.7 and 12.6 microg/ ml, respectively). CONCLUSION: The results obtained for anti-inflammatory and antioxidant activities of these plants correspond with their traditional use for muscle pain and inflammatory-related diseases.
