The methanol, ethanol and water extracts showed lessThan /i greaterThan lessThan i greaterThan in vitro lessThan /i greaterThan lessThan i greaterThan anti-inflammatory activity by inhibiting the heat induced albumin denaturation is 86.32, 83.81, 61.39 g/ml and red blood cells membrane stabilization with 71.29, 67.78, 54.48 g/ml respectively. Proteinase activity was also significantly inhibited by the methanol (83.91), ethanol (81.88) and water (61.73). In addition, the methanol and ethanol extracts showed anti-lipoxygenase activity range from 39.32-58.92. The study also showed that methanol and ethanol fractions exhibited a moderate xanthine oxidase inhibitory activity comparatively to the acetylcholinestearse which was weakly inhibited by the tested extracts. The results obtained in the present investigation indicate that methanol and ethanol extracts of lessThan /i greaterThan lessThan i greaterThan T. stans lessThan /i greaterThan lessThan i greaterThan can be a potential source of anti-inflammatory agents. lessThan /i greaterThan Govindappa M., Sadananda T.
