 "Essential oils extracted from the leaves are used in aromatherapy and perfumes." [[https://en.wikipedia.org/wiki/Abies_sibirica]]
+Siberian fir oil has been described as having a very pleasant smell. Main components of three oils from Austria, Italy, and Korea were α-pinene (24.1-24.5%), β-pinene (2.8-6.9%), limonene (12.6-41.5%), and camphene (22.7-54.8%). \\
+"Having the same amount of α-pinene, its enantiomers are different in Italian and Korea oils in comparison  with that from Austrian. In the Austrian oil, the (+)isomer is dominating, but the (-)isomer dominates in
+Korea and Italian oils. Quite a different situation dominates in the case of camphene and limonene. Those  two compounds occur, independent of their origin, as chiefly (-)isomers." \\

 "Participants who breathed air containing the essential oil showed prolonged heartbeat intervals and increased theta activity as measured by electroencephalography in the recovery period after the VDT task, but not during the task. The volatile constituents emitted from the essential oil of A. sibirica through the odorant delivery system for 40 min were α-pinene (80.4 µg), santene (3.1 µg), tricyclene (2.4 µg), camphene (24.2 µg), β-pinene (2.6 µg), myrcene (1.0 µg), δ-3-carene (14.4 µg), limonene (3.8 µg), and [[https://de.wikipedia.org/wiki/Essigs%C3%A4urebornylester|bornyl acetate]] (1.0 µg)." \\

 The essential oil isolated from Abies sibirica needles contained bornylacetate (34.2%), camphene (17.4%), α-terpinene (6.7%), α-pinene (5.9%), limonene (5.5%) and borneol (2.9%) as major constituents. "The contents of the constituents in various fractions changed during production of the essential oil depending on the distillation time... the biological activity of A. sibirica essential oil depended largely on the contents of the major constituents such as bornylacetate and camphene." \\
