Abstract

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.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.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 8(th) 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 11(th) 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.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.A. americana possess protective effect against acetic acid-induced colitis in rats.
