The wood oils of Pinus jeffreyi and P. sabiniana contain considerable amounts of heptane (76.6%, 92%), on a monoterpene basis. However, when entire wood extractables is considered, the amounts drop considerably (3.4%, 36.8%) with the major portion of the wood oils being diterpene acids. The leaf oil of P. jeffreyi is dominated by α-pinene (20.9%) and, a diterpene, thunbergol (9.2%) with moderate amounts of β-pinene, δ-3-carene, limonene, β-phellandrene, (Z)-β-ocimene, (E)-caryophyllene, δ-cadinene and cembrene. The leaf oil of P. sabiniana is dominated by α-pinene (39.1%) with moderate amounts of β-pinene, myrcene, limonene, β-phellandrene, (Z)-β-ocimene, methyl chavicol, decanal and thunbergol.
