fragrantissima oil is rich with sesquisabinene hydrate, bisabolene epoxide, camphor, and caryophyllene oxide; also limonene, menthol, azulene, and thujone are found in moderate amount, while santolina alcohol, lanceol, cedrene
, and granny geraniol are found in a minor amounts (Table 1).
Their trypanocidal activities are in the decreasing order of activity: cedrene
> caryophyllene > limonene.
cedrene alcohols and clovan diol) increased or appeared for the first time in the chloroform extract.

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).
