International audience. Morus mesozygia Stapf (Moraceae) is a plant found in many regions and used in treating many diseases including malaria and fever. Fractionation of the methanolic extract of its stem bark, using various chromatographic methods has led to the isolation and identification of 3 flavonoids: artocarpesin, artochamin C and kushenol E. And 4 arylbenzofuran derivatives: moracin M, moracin C, moracin L and mulberofuran F. The methanolic extract and the seven isolated compounds were tested for antiplasmodial activity against the chloroquine-resistant FcB1 Plasmodium falciparum strain and cytotoxicity on MCF-7 human breast cancer cells. Relating to the antiplasmodial activity, it was found that all compounds were active against the FcB1 strain of Plasmodium with artocarpesin, koushenol E and mulberrofuran F showing particular potency (with the median inhibitory concentrations IC50 = 2.5- 2.6 \textmug/ml). Cytotoxicity tests performed on MCF
