Abstract
The water distilled oils from the aerial parts of Salvia compressa Vent. collected from two different localities and Cyclotrichium leucotrichum (Stapf. ex Rech.f.) were analyzed by GC and GC/MS. The main components found in the oil of S. compressa collected at Tange Malavi, 751 m (sample A) were β-caryophyllene (21.4%), α-pinene (18.4%) and caryophyllene oxide (13.2%), while in the oil of the plant collected at Mamolan to Pole Dokhtar, 927 m (sample B), β-caryophyllene (21.1%), 3-thujopsanone (15.3%), germacrene D (12.6%), bicyclogermacrene (11.6%) and nerol (10.7%) were the most abundant constituents. Both oils were richer in sesquiterpenes than monoterpenes. Linalool (38.7%), limonene (15.4%) and spathulenol (12.6%) were the predominant compounds in the oil of Cyclotrichium leucotrichum. The oil of the plant consisted mainly of monoterpenes.
