Abstract

The essential oils from the leaves and twigs of Juniperus horizontalisand Juniperus scopulorum, growing in southwestern Idaho, were obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry (GC-MS) and gas chromatography–flame ionization detection (GC(FID)). The major components in the essential oil of J horizontaliswere α-pinene, 16.9%, predominantly ( + )-α-pinene; sabinene, 37.1%, exclusively ( + )-sabinene; myrcene, 5.0%; and terpinene-4-ol, predominantly ( + )-terpinen-4-ol. The essential oil of J scopulorumwas rich in sabinene, 29.8%, exclusively ( + )-sabinene; terpinene-4-ol, 13.2%, nearly racemic; α-elemol, 9.7%; and 8α-acetoxyelemol, 6.4%. In addition, 12 commercial Juniperus communisfruit essential oils were analyzed by chiral GC-MS. α-Pinene showed considerable variation in enantiomeric distribution, depending on geographical location. The dominant enantiomer of sabinene in J communisessential oils was ( + )-sabinene.
