 "The composition of the leaf oils of Juniperus rigida from northeast China, Japan and Korea are reported. The Japanese samples were very similar to previous literature reports being rich in [[http://www.takasago.com/cgi-bin/detail.cgi?key=C134031|bornyl acetate]] (40.5–59.0%) and α-pinene (13.5–15.4%), but the samples from northeast China and Korea showed geographical differentiation in the production of increased amounts of α-pinene (39.7% and 53.5% respectively) and reduced amounts of bornyl acetate (1.3% and 2.8% respectively)." \\
-R.P. Adams found α-pinene (39.7%) as the main component in the essential oil from the leaves of a J.rigida tree from the Botanical garden of Beijing (origin = ne China). Myrcene (11.2%), 2-undecanone (4.8), limonene (4.2), germacrene D (2.3%) were also present. The amount of bornyl acetate was reduced to 1.3%. \\
