Abstract
Sagebrush species, including Artemisia
tridentata, Artemisia ludoviciana, Artemisia frigida, and Artemisia
cana, are conspicuous features of the intermountain western region of North
America. As part of our interest in the volatile phytochemistry of aromatic and
medicinal plants, including sagebrush, of the western United States, we
obtained and analyzed the essential oils of Artemisia tridentata subsp. vaseyana
and Artemisia cana subsp. viscidula from the Sawtooth Valley of
central Idaho. Essential oils were obtained by hydrodistillation and analyzed
by gas chromatography – mass spectrometry. The essential oil of A.
tridentata subsp. vaseyana was dominated by fragranol (55.8-70.0%)
and fragranyl acetate (24.1-30.0%). The major components of A. cana
subsp. viscidula were (2E)-1,3,7-trimethyl-2,6-octadienyl acetate
(33.7-38.2%) and ethyl trans-chrysanthemumate (7.8-26.3%), along with
two major unidentified components (4.8-12.1% and 6.1-8.5%). The essential oil
compositions of these two sagebrush species are remarkably different from those
previously published and illustrate the complexity and variability of sagebrush
volatile components.

Sagebrush species, including Artemisia

obtained and analyzed the essential oils of Artemisia tridentata subsp. vaseyana
and Artemisia cana subsp. viscidula from the Sawtooth Valley of

by gas chromatography – mass spectrometry. The essential oil of A.
tridentata subsp. vaseyana was dominated by fragranol (55.8-70.0%)
and fragranyl acetate (24.1-30.0%). The major components of A. cana
subsp. viscidula were (2E)-1,3,7-trimethyl-2,6-octadienyl acetate
(33.7-38.2%) and ethyl trans-chrysanthemumate (7.8-26.3%), along with
two major unidentified components (4.8-12.1% and 6.1-8.5%). The essential oil
compositions of these two sagebrush species are remarkably different from those
previously published and illustrate the complexity and variability of sagebrush
volatile components.
