AUTHOR(S): Kathy Swor, Ambika Poudel, Prabodh Satyal and William N Setzer
ABSTRACT:The essential oil was obtained from the foliage of Juniperus occidentalis collected from Leslie Gulch, southeastern Oregon, by hydrodistillation. Gas chromatographic analysis revealed a total of 120 identified components with bornyl acetate (36.8%), p-cymene (9.9%), terpinen-4-ol (7.6%), and sabinene (6.2%) as major components. Enantioselective gas chromatography showed, for the first time, that (+)-?-pinene, (+)-camphene, (+)-sabinene, (+)-?-pinene, (+)-?-3-carene, (+)-limonene, (+)-cis-sabinene hydrate, (+)- camphor, (+)-terpinen-4-ol, (+)-borneol, and (+)-?-terpineol were the predominant enantiomers in J. occidentalis essential oil.
