Gas chromatography-mass spectrometry analysis identified skeletons of sesquiterpenes and sesquiterpene alcohols in both extracts and the most abundant compounds identified, cedrol, cedrenes, and thujopsenes, were individually screened for antifungal activity.
The antitermite compounds are reported to be cedrenes and sesquiterpenes of a 15-carbon skeleton (Karchesy 1998).
