Evaluation of the Antidiarrheal Activity of Hydromethanol Crude Extracts of Ruta chalepensis and Vernonia amygdalina in Mice.

ABSTRACT: Background:The herbal medicine practitioners in Ethiopia have used a wide range of medicinal plants as antidiarrheal agents. Among these, Ruta chalepensis and Vernonia amygdalina were claimed to have antidiarrheal activity in Ethiopian folklore medicine. Hence, the aim of the present study was to evaluate the antidiarrheal activity of the crude extracts of Ruta chalepensis and Vernonia amygdalina in mice. Methods:The crude extracts were obtained by cold maceration with 80% methanol, and its antidiarrheal activities were evaluated using a castor oil-induced diarrheal model. The test groups were treated with 100, 200, and 400?mg/kg body weight (bw) of the crude extract of each plant, while the positive controls and negative controls were given loperamide (3?mg/kg.bw) and 2% Tween 80 (10?ml/kg.bw), respectively. Results:In the castor oil-induced model, the crude extract of Ruta chalepensis (200 and 400?mg/kg.bw) significantly prolonged the onset of diarrhea in mice. Besides, it also showed a significant reduction in the frequency of stooling and weight of feces. Contrastingly, the crude extract of Vernonia amygdalina had a significant effect in delaying the onset of time of diarrhea and reduction of the frequency of stool and the weight of feces only at the maximum tested dose (400?mg/kg.bw). Conclusion:The present study demonstrated that the crude leaves extract of Ruta chalepensis (200 and 400?mg/kg.bw) and Vernonia amygdalina (400?mg/kg.bw) possessed significant antidiarrheal activity in the castor oil-induced diarrheal model.
