Abstract

The International Centre for Insect Physiology and Ecology (ICIPE), P.O. Box 30772, Nairobi.
The essential oil isolated by hydrodistillation from leaves of Croton sylvaticus Hochst (0.14 %) was analyzed by GC and GC-MS. Over 52 components, constituting about 86.3 % of the oil, were separated. The major constituents were P-caryophyllene oxide (35.1 %) and a-humulenl,2-epoxide (12 %). The petroleum ether extract of the stem bark yielded (-)-hardwickic acid, (3 - sitosterol, stigmasterol and ent-83- 15,1abd- 13-en (E)-diol.
