| "Monoterpenoids and sesquiterpene hydrocarbons of Abies balsamea cortical oleoresin (Canada balsam) were analyzed by a combination of chromatographic and spectroscopic methods. Monoterpene hydrocarbons (21%) were composed of β-pinene, α-pinene, β-phellandrene, limonene, 3-carene, myrcene and camphene (listed in order of decreasing percentages), and oxygenated monoterpenes (0·4%) contained 4,4-dimethyl-2-cyclohepten-1-one, linalool, bornyl acetate, methylthymol, citronellyl acetate, α-terpineol, piperitone, citronellal, borneol, citronellol, two unknowns, and geraniol. From the sesquiterpene hydrocarbon fraction (1·1%) were isolated: longifolene, β-bisabolene, longipinene, an unknown, sativene, cyclosativene, cis-α-bisabolene, β-himachalene, α-himachalene, β-caryophyllene, γ-humulene, farnesene, longicyclene, an unknown, and β-selinene. Both himachalenes have been identified for the first time in Pinaceae outside of Cedrus; their co-occurrence with γ-humulene, longifolene, longipinene and longicyclene supports the biosynthetic mechanism by which all of these compounds arise through initial 1/11 cyclization of tran-cis-farnesylphosphate." \\ | "Monoterpenoids and sesquiterpene hydrocarbons of Abies balsamea cortical oleoresin (Canada balsam) were analyzed by a combination of chromatographic and spectroscopic methods.
