activities against pest and ethyl acetate extracts of leaves and stems of snail galba truncatula from capparis spinosa

摘要

the activity against some plant is one of the most effective ways to break the cycle of the cycle tru00e9madoses which involves a gastropod species. snail galba truncatula is, in the case of the trematode parasite fasciola hepatica.the ethyl acetate extracts of leaves and stems, and the fraction of the methanol extract with ethyl acetate sheets of capparis spinosa exhibited molluscicidal activity to kill 50% lethal doses, shellfish lc50 = 8.03 mg / l with an interval the trust (0.070, 14,16) mg / l (95%), and lc = 8.79 mg / l with a confidence interval of (6)65; 9.7%) mg / l (95%), and lc = 3.53 mg / l with a confidence interval of 1.65; 4, u00ac66) mg / l (95%) after two days.using the same lethal doses on molluscs affected by larval stages of fasciola hepatica is a pesticide activity with a decay rate in excess of 30% (30,39, 91.52) in the larval stages. intraru00e9diennes rediae and cercariae, cell bodies.the activity could be related to hold sterols and / or carotenoids content in ethyl acetate extracts of leaf and stem of capparis spinosa in the methanol fraction of the ethyl acetate extract of the leaves of capparis spinosa, the shellfish scicide could be related to flavonoids and saponins were present.
