The chemistry of five African Croton taxa, Croton oligandrus Pierre ex Hutch., Croton megalocarpus Hutch., Croton menyharthii Pax, Croton rivularis Mull.Arg. and Croton megalobotrys Mull.Arg. is described. The undescribed ent-19-hydroxyisopimara-8(9),15-dien-7-one and ent-isopimara-7(8),15-dien-16,19-diol were isolated from the fruits of C. oligandrus, ent-isopimara-7(8),15-dien-19-yl octadecanoate
