In vitro ovicidal and larvicidal activity of the essential oil of Artemisia lancea against Haemonchus contortus (Strongylida).
The anthelmintic potentials of the chloroform and methanol extracts of Buchholzia coriacea Engler seed were investigated. In folklore medicine, B. coriacea (Capparidaceae) is believed to be useful in the treatment of various kinds of ailments and diseases. At doses of 10 mg/kg, 25 mg/kg and 50 mg/kg, the extracts were tested against Eudrilus eugeniae (earthworm) and Bunostomum phlebotomum (cattle hookworm). The extracts exhibited dose-dependent anthelmintic effects on the earthworms and hookworms. The methanol extract at 50 mg/kg was the most active extract against the helminths, and the activity of the methanol extract was not significantly different from that of piperazine hydrate (reference drug, 10 mg/kg) against the earthworms.
