Toxicity and Antiparasitic Efficacy of Essential Oils: Analyses of the Biochemical Compositions and Potencies

Background: Hydatidosis is a common disease of both humans and animals, resulting from infection with the larvae Echinococcus granulosus tapeworm. The aim this study was to investigate antiparasitic (protoscolicidal) activities three essential oils in vitro. Methods: This designed evaluate biochemical composition vitro effects Zataria multiflora, Origanum vulgare Mentha pulegium oils. Gas chromatography performed identify main components herbal To determine properties oils, live protoscoleces hydatid cysts were exposed concentrations incubated at 37°C for 5, 10, 15, 20 or 25 minutes. Results: analysis these indicated that carvacrol thymol major compounds oil. Further, oil pulegone piperitone compounds. quickest slowest effect achieved (10%) (0.6%), respectively. statistical showed significant difference between mortality rate 0.6% 1% concentrations, respectively, predetermined exposure times (P<0.05). had same differences Conclusion: Essential protoscolicidal dependent on concentration times.
