Abstract

Four new Xanthones, butyraxanthones A-D (1-4), were isolated from the stem bark of Pentadesma butyracea, together with six known Xanthones (5-10) and a triterpenoid (lupeol). The structures of 1-4 were established by spectroscopic methods. Compounds 1-10 were tested in vitro for antiplasmodial activity against a Plasmodium falciparum chloroquine-resistant strain and for cytotoxicity against a human breast Cancer cell line (MCF-7). Nearly all of these Xanthones exhibited good antiplasmodial activity, and some of them also demonstrated potent cytotoxicity.
