Chemical composition of the aerial parts essential oil of Chrysothamnus viscidiflorus from southwestern Idaho

Abstract

Yellow rabbitbrush (Chrysothamnus viscidiflorus) is native to the Great Basin of North America and the plant was part of the traditional medicine of Native Americans in the region.There has been very little previous work on essential oils of Chrysothamnus, and no reports on C. viscidiflorus essential oil.Therefore, the purpose of this work was to evaluate the chemical composition of C. viscidiflorus essential oil.The aerial parts of C. viscidiflorus were collected from southwestern Idaho, the essential oil obtained by hydrodistillation and analyzed by gas chromatographic methods.The essential oil was obtained in 1.121% yield and was dominated by monoterpene hydrocarbons (82.6%), including (-)--pinene (41.3%), (+)-limonene (17.4%), (+)-sabinene (9.1%), myrcene (4.2%), and (E)--ocimene (4.2%).This is the first report on the essential oil characterization of C. viscidiflorus, and adds to our understanding of the volatile phytochemistry of Chrysothamnus.Biological activities of the major components in the essential oil are consistent with the traditional Native American use of the plant.
