Abstract
Based on the results of ethnomedical and ethnoveterinary surveys that we had carried out in northern Côte d'Ivoire during 1999–2001, 79 plant species belonging to 36 families were selected for in vitro. anthelmintic screening. The activity of ethanol crude extracts was investigated using the nematode Haemonchus contortus. Rudolphi (1803) as the test species. Of 115 extracts tested, 50 showed larvicidal activity and two were ovicidal. The most active came from Sclerocarya birrea. (A. Rich) Hochst followed by Lannea kerstingii. Engl. & K. Krause, Aframomum alboviolaceum. (Ridely) K. Schum., Pericopsis laxiflora. (Benth) van Meeuwen, Pseudocedrela kotschyi. (Schweinf.) Harms, Securidaca longepedunculata. Fres., Alchornea cordifolia. (Schum. & Thonn.) Müll. Arg., Anthostema senegalense. A. Juss, Ficus vallis-choudae. Del., Ampelocissus grantii. (Lour) Merrill, Vitellaria paradoxa. C. F. Gaertn, and Hibiscus asper. Hook f. The results supported the traditional uses of some of the tested plants in the treatment of intestinal helminthosis. As Haemonchus contortus. is a pathogenic nematode in small ruminants, the active plant species could be a potential source of new lead anthelmintic agents.
