Studies on antidiarrhoeal activity of Jatropha curcus root extract in albino mice.

Use of Jatropha curcus L. roots in the treatment of diarrhoea is a common ethnobotanical practice in Konkan, a part of the Western coastal area of India. Roots of this species were undertaken for pharmacognostic studies and evaluation of antidiarrhoeal activity in albino mice. Successive solvent extraction was carried out using petroleum ether (60-80 degrees C) and methanol. The methanol extract showed activity against castor oil induced diarrhoea and intraluminal accumulation of fluid. It also reduced gastrointestinal motility after charcoal meal administration in albino mice. The results indicate that action of J. curcus root methanol extract could be through a combination of inhibition of elevated prostaglandin biosynthesis and reduced propulsive movement of the small intestine.
