The Essential Oil Compositions of Ambrosia acanthicarpa Hook., Artemisia ludoviciana Nutt., and Gutierrezia sarothrae (Pursh) Britton & Rusby (Asteraceae) from the Owyhee Mountains of Idaho

As part of our interest in the volatile phytoconstituents of aromatic plants of the Great Basin, we have obtained essential oils of (three samples), (12 samples), and (six samples) from the Owyhee Mountains of southwestern Idaho. Gas chromatographic analyses (GC-MS, GC-FID, and chiral GC-MS) were ca...

Description
Summary:As part of our interest in the volatile phytoconstituents of aromatic plants of the Great Basin, we have obtained essential oils of (three samples), (12 samples), and (six samples) from the Owyhee Mountains of southwestern Idaho. Gas chromatographic analyses (GC-MS, GC-FID, and chiral GC-MS) were carried out on each essential oil sample. The essential oils of were dominated by monoterpene hydrocarbons, including α-pinene (36.7-45.1%), myrcene (21.6-25.5%), and β-phellandrene (4.9-7.0%). Monoterpene hydrocarbons also dominated the essential oils of , with β-pinene (0.5-18.4%), α-phellandrene (2.2-11.8%), limonene (1.4-25.4%), and ( )-β-ocimene (18.8-39.4%) as major components. The essential oils of showed wide variation in composition, but the relatively abundant compounds were camphor (0.1-61.9%, average 14.1%), 1,8-cineole (0.1-50.8%, average 11.1%), ( )-nerolidol (0.0-41.0%, average 6.8%), and artemisia ketone (0.0-46.1%, average 5.1%). This is the first report on the essential oil composition of and the first report on the enantiomeric distribution in an species. The essential oil compositions of and showed wide variation in composition in this study and compared with previous studies, likely due to subspecies variation.
