TL;DR: Four new xanthones, butyraxanthones A-D (1-4), were isolated from the stem bark of Pentadesma butyracea and exhibited good antiplasmodial activity, and some of them also demonstrated potent cytotoxicity.

TL;DR: Eight extracts from seven selected Cameroonian medicinal plants, traditionally used to treat malaria and other protozoal diseases, were tested in vitro for their antiprotozoal activities against Plasmodium falciparum K1 chloroquine-resistant strain and Trypanosoma brucei rhodesiense, protozoa responsible for malaria, visceral leishmaniasis, Chagas disease and African trypanosomiasis.

TL;DR: Although the leishmanicidal activity of the methanolic extracts of Allanblackia monticola and Symphonia globulifera is promising, the cytotoxicity profile of these compounds prevent at this state further in vivo biological evaluation.

TL;DR: Phytochemical investigation of the stem bark of Beilschmiedia zenkeri led to the isolation of four new methoxylated flavonoid derivatives, which were evaluated in vitro for their antibacterial activity against three strains of bacteria and for their antiplasmodial activity against Plasmodium falciparum, chloroquine-resistant strain W2.

TL;DR: It's concluded that Mondia whitei had sexual enhancement of the sexually inexperienced male rat and was found to be more efficient than the aqueous extract.
