 "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.

 Main volatiles found in the headspace of balsam fir needles powder were α-pinene, camphene, β-pinene, δ-3-carene, β-phellandrene, and bornyl acetate. Minor ones were tricyclene, β-myrcene, terpinolene, maltol, camphor, borneol, myrtenal, piperitone, longifolene, α-longipinene, β-caryophyllene, α-humulene, and α-bisabolene. \\ Main volatiles found in the headspace of balsam fir needles powder were α-pinene, camphene, β-pinene, δ-3-carene, β-phellandrene, and bornyl acetate.

 +"Gas chromatography/mass spectrometry (GC/MS) of Abies balsamea, [[picea_mariana_mill._britton_et_al|Picea mariana]] and [[tsuga_canadensis_l._carr|Tsuga canadensis]] leaf essential oils assigned bornyl acetate as a major peak in A.balsamea and P.mariana, while isobornyl acetate was identified  as the major peak in T.canadensis. Though these two isomers elute closely on GC, their characteristic mass spectra allow unequivocal structural assignment...\\
