 "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)." \\ "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 essential oil isolated from Abies sibirica needles contained bornylacetate (34.2%), camphene (17.4%), and α-terpene (6.7%) 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." \\ The essential oil isolated from Abies sibirica needles contained bornylacetate (34.2%), camphene (17.4%), and α-terpene (6.7%) as major constituents.
