Effect of water extract of leaves of castor, tomato, and eggplant plants in the vitality of the initial visions of granular movements of sheep in vitro

The present study revealed significant effect of the aqueous extract of the leaves of Ricinus communis at the concentrations 10,20,30, 40mg/ml of Datura innoxia, and Solanum melongena at the concentrations 50,100,150 and 200 mg/ml,respectvely on the viability of protoscoleces of Echinococcus granulosus of sheep origin. The concentration 40 mg/ml of R.communis leaves caused the death of all protoscoleces within 30 minutes ,while the concentrations 100 and 200 mg/ml of D. innoxia and S.melongena caused the death of all protoscoleces within 60 minutes. The inhibitory effects of these extracts were proportional with their concentrations and the time of exposure.
