title: Composition of the essential oil of Helichrysum chasmolycicum growing wild in Turkey.
abstract: The chemical compositions of the essential oil obtained from the aerial parts of Helichrysum chasmolycicum were analyzed by gas chromatography and gas chromatography-mass spectrometry. From the 57 identified constituents, representing 66.55% of the oil, the main constituents of the oil were beta-caryophyllene (27.6%), beta-selinene (8.9%), alpha-selinene (8.4%), caryophyllene oxide (7.3%), and carvacrol (2.4%). The essential oil was almost totally characterized by sesquiterpene hydrocarbons such as beta-caryophyllene and alpha- and beta-selinene.
