Abstract:

Description
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 was obtained from both the fruits and leaves, and ent-19-hydroxyisopimara-8(9),15-dien-7-one was isolated from the leaves of this species. The undescribed 3,4,15,16-diepoxy-8α-hydroxycleroda-13(16),14-dien-12S,17-olide and (5S,9R,10S)-7,13-ent-abietadien-2-one were isolated from the leaves and roots of C. megalocarpus respectively. Compounds isolated from C. menyharthii, C. rivularis and C. megalobotrys have been reported from other sources. The structures of the compounds were determined using …
