Juniperus occidentalis

In 1973, Tatro et al (11)examined the qualitative and quantitative changes in essential oil composition of leaf oils obtained from Juniperus occidentalis, J. osteosperma and J, californica, and found that neither growth medium or seasonal variation had a significant effect on oil composition. By contrast, they observed a definite diurnal cycling which they attributed to the fluctuation in air temperature over a twenty-four hour period. Six years later, Hopfinger et al (16) examined the diurnal variation in the leaf oil of Citrus sinensis (L.) Osbeck. The authors found that there was a two-fold diurnal change in oil...

Fenchane derivatives occur as fenchones and fenchols in several ethereal oils. Oil of fennel, obtained from the dried fruit of Foeniculum vulgare (Umbelliferae), contains up to 20 % (+)-fenchone, and is associated with limonene, phellandrene and a-pinene. (-)-Fenchone is isolated from the tree of life Thuja occidentalis (Cu-pressaceae), which is cultivated as hedges. The dextrorotatory enantiomer of a-fenchol with an endo OH, requested in perfumery, as well as its stereoisomers are found in fresh lemon juice, in oil of turpentine obtained from Pinus palustris (Pina-ceae), in ethereal oils originating from the Lawson white cedar Chamaecyparis lawsoniana (Cupressaceae) and other plant families such as Ferula, Juniperus, and Clausena species...
