Introduction: Natural plants always provide core compounds for new drug development. In the present life and food style, inflammatory bowel disease has become common and needs a lead compound for its drug development.Aim: To evaluate the effect of Agave americana Linn. leaf extract in acetic acid-induced ulcerative colitis in rats based on its traditional anti-inflammatory use. Materials and Methods: Male Wistar rats were pretreated with A. americana leaf extract in the dose of 200 and 400 mg/kg p.o. daily for 7 days. On 8th day, 2 ml of 4% v/v acetic acid in saline was instilled into rats' rectum. Prednisolone was used as standard drug and it was administered on the day of acetic acid instillation and continued for 3 days. Extract treatment was continued till 11th day. Body weight, ulcer score, colonic muscle contraction, antioxidant activity and histopathology were studied. Statistical analysis was performed using Parametric one-way analysis of variance followed by Tukey's posttest. Results: A. americana have retained total body weight significantly (P < 0.01) and decreased colon weight/length ratio. Extract have shown a significant decrease (P < 0.001) in ulcer scores, myeloperoxidase, lipid peroxidase activity. Further, extract have shown significant improvement in colonic muscle contraction, histopathology of colon etc., which is comparable with standard drug. Conclusion: A. americana possess protective effect against acetic acid-induced colitis in rats.
