Background  With the aim of discovering new natural active extracts against malaria parasites,  Icacina senegalensis  was selected after an ethnopharmacological survey conducted on plants used in traditional malaria treatment in Senegal.    Methods  Different concentrations of the plant extract and fractions were tested on synchronized  Plasmodium falciparum  cultures at the ring stage using the parasite lactate dehydrogenase assay. Their haemolytic activity and  in vitro  cytoxicity were evaluated. The chromatographic profiles of active fractions were also established.    Results  The plant extract and fractions revealed anti-plasmodial activity (IC 50  < 5 μg/mL) with no toxicity (Selectivity indexes >10). The dichloromethane fraction showed stronger anti-plasmodial activity than the total extract.    Conclusion  Anti-plasmodial activity and toxicity of  I. senegalensis  are reported for the first time and showed promising results in malaria field research.
