The present master thesis describes the phytochemical study and the antiplasmodial activity against Plasmodium falciparum (W2) of Himatanthus articulatus (Vahl) Woodson. The ethanol extract (EEHS) obtained by percolation of the bark powder, gave, after concentration, a precipitate (EEHSP) and a pasty residue that was submitted to lyophilization (EEHS). Fractionation of EEHS was carried out by successively re-extraction with DCM, AcOEt and MeOH under reflux, by acid-base partitioning for separation of alkaloids and by chromatography over silica gel column. Furthermore, the bark powder was extracted with 1 N HCl for the separation of alkaloids. TLC prospection of EEHS and EEHSP was carried out while EEHS, FrDCM EEHS, FrAcOET EEHS, FrMeOH EEHS...
