The first comprehensive report on the compositions of the volatile leaf terpenoids of Pinus contorta var. contorta, var. latifolia and var. murrayana are presented. The volatile leaf oils of vars. contorta and latifolia were nearly identical, dominated by B-phellandrene (54.6, 45.1%), with moderate amounts of B-pinene (8.7, 10.3%), a-phellandrene (4.9, 1.7%), a-pinene (3.7, 3.4%), myrcene (1.9, 2.1%), o-3-carene (0.9, 11.5%), a-terpene (3.7, 1.6%) and terpinolene (3.7, 2.0%). With the exception of o-3-carene (0.9, 11.5%), they differ only in minor compounds: camphor (0.2, trace), methyl chavicol (none, 0.4%), (E)-anethole (none, 0.5%), dodecanoic acid (0.6, trace), and sandaracopimarinal (0.3, trace). The oil of var. murrayana is considerably different from that of vars. contorta and latifolia. The volatile leaf oil of var. murrayana is dominated by B-pinene (38.1%) and B-phellandrene (18.2%) with moderate amounts of a-pinene (5.2%), myrcene (1.8%) and o-3-carene (5.9%) and 7 unique components: citronellal, citronellol, geraniol, methyl eugenol, a C10-diene acetate, elemicin, and sandaracopimarinol. The major components (as percent total oil) were very variable for all three taxa.
