juniperus_occidentalis

Juniperus occidentalis Hook. - Cupressaceae - Western Juniper, Sierra Juniper, Westamerikanischer Wacholder

Shrub or tree, native to western North America. (US: Oregon and Washington).

„The essential oil obtained from the heartwood is used as an fragrance component in soaps, sprays and disinfectants as well as as an immersion oil in microscopy.“ https://de.wikipedia.org/wiki/Westamerikanischer_Wacholder

„The crude oil, as recovered, was a dark-red, opaque liquid. The odor was somewhat harsh, suggestive of the odor of the foliage or bark… [Wood] Oil recovery averaged around 1.4%, of which about 15-40% was cedrol… The oils from high-pressure runs, when treated by the Raybak process (Guentherp. 300 Vol I) yielded about 20-25% of the weight of oil as crystalline cedrol.“ [Kurth, Ervin Frank, and John Daryl Ross. „Volatile oil from western juniper.“ (1954)] https://ir.library.oregonstate.edu/downloads/c247ds142

Main components of the essential oil extracted from the wood of J.occidentalis var.occidentalis were cedrol (38.9%), thujopsene (18.9%), α-cedrene (8.8%), β-cedrene (2.6%), widdrol (1.6%), and cuparene (1.5%).
