Fig. 4From: Ethnobotanical survey, anthelmintic effects and cytotoxicity of plants used for treatment of helminthiasis in the Central and Kara regions of TogoAnthelmintic effect of Xylopia aetiopica (XA), Aframomum melegueta (AM) and Khaya senegalensis (KS) on microfilariae (Mf) of Litomosoides sigmodontis. Mf (nā=ā75/well) of Litomosoides sigmodontis were cultured in absence of plant extracts (0āĪ¼g/ml, medium) or in presence of AM (green line), KS (blue line) and XA (red line) at different concentrations (200āĪ¼g/ml, 500āĪ¼g/ml and 1000āĪ¼g/ml). After 7ādays culture, the viability of microfilariae were evaluated using typan blue. Graph shows the percentage of dead Mf for each concentration. The concentration that induced 50% of death was designed lethal dose 50 (LD50)Back to article page
