Effect of Ethanolic Extract and Crude Alkaloides of Peganum harmala Seeds on The Viability of Echinococcus granulosus Protoscolices in vitro

The crude ethanolic extract and crude alkaloids of Peganum harmala seeds were prepared, the scolicidal effect of these extracts on the protoscolices of Echinococcus granulosus in vitro were determined at 4C and 37C at different time intervals.
Both extracts exerted higher effect at 37C, and the crude alkaloid extract was more effective than the ethanolic extract as it gave a scolicidal effect at a concentration of 31 mg/ml and it i also exerted a complete scolicidal effect at (48-72) hrs. which was similar to the effect of mebendazole.
