The chemical composition of the essential oils obtained from aerial parts of Scutellaria orientalisL. ssp. alpina(Boiss.) O. Schwarz and S. utriculataLabill. growing wild in Lebanon, were analyzed by GC and GC-MS. In S. orientalisssp. alpina, strongly characterized by sesquiterpenes (41.2%) and particularly sesquiterpene hydrocarbons (31.7%), hexahydrofarnesylacetone (11.7%) was recognized as the main constituent, together with hexadecanoic acid (7.6%), caryophyllene (7.4%), caryophyllene oxide (6.8%), 4-vinylguaiacol (5.4%) and germacrene D (5.4%). S. utriculataoil was instead constituted above all by monoterpenes (42.2%), particularly oxygen containing monoterpenes (39.9%), and in this oil the main compounds were linalool (20.1%), 4-vinyl guaiacol (15.5%), α-terpineol (8.9%), (E)-nerolidol (8.9%) and geraniol (8.2%).
