The aim of the study was to evaluate the effect of Pterocarpus marsupium (PM) on acetic acid (AA)-induced ulcerative colitis (UC) in rats. The rats were divided into five groups, each having six rats. PM extract 100 mg and 200 mg/kg was given orally to groups four and five, respectively, and standard drug sulfasalazine (100 mg/kg, p.o) to group three. Group two served as UC control animals, and group one control animals received vehicle for 7 days. UC was induced by administering AA (3 % v/v of 2 ml) toall the animals except group one. After 72 h, the animals were killed and the colon was dissected out for microscopic, clinical evaluation, histopathological study and biochemical estimation. PM (100 and 200 mg/kg)-treated group had significantly reduced colon inflammation and mucosal damage. Thetreatment also normalized the altered antioxidant enzyme levels (LPO, SOD and GSH). Histopathological studies support the effect. The protective effect of PM may be due to antiinflammatory and antioxidant properties.
