Abstract

Phytochemical analysis by GC and GC/MS of the essential oil samples, obtained from fresh aerial parts, shoots and inflorescences of Geocaryum cynapioides (Guss.) L. Engstrand, allowed the identification of 55 components in total, comprising 99.5%, 99.7% and 99.0% of the oils compositions, respectively. Regarding the aerial parts essential oil, the major of 52 identified volatile compounds were (E)-β-Farnesene (66.6%), 7-epi-cis-Sesquisabinene hydrate (17.4%) and (E,E)-α-Farnesene (3.7%). The same compounds were dominant among the 48 components detected in the shoots and 42 volatiles in inflorescences oil, but in different proportions. Hydrocarbon sesquiterpenes had the highest contribution in all investigated Geocaryum cynapioides essential oils, with a share of about three quarters of all, followed by one quarter of oxygenated sesquiterpenes, while the monoterpenoid and nonterpenoid compounds were detected only in trace amounts
