Thin layer chromatography (TLC) analysis revealed that destructive distillation of Juniperus procera tree gave .en
major components, whereas Croton megalocarpus tree yielded five components. This was confirmed by gas chromatography
(GC). The components were isolated by column chromatography and analysed using infrared, ultra-violet,
visible and mass spectroscopy (MS) techniques. The whole extract was about 30.3% of the starting material (sawdust)
and consisted of 77.5% water arid 22.5% oily reddish-brown layer. The extracts had alcoholic and phenolic compounds
together with acids. Cedrol, a tertiary tricyclic alcohol, was found to be in the greatest proportion in the oily layer. IR
spectra with a peak beyond 3000cm:, UV-VIS absorption maxima at 230 nm and mass spectra with mle 204 suggested
the presence of cedrene in the extract
