Abstract
Mature Juniperus oblonga M. Bieb. fruits growing in Dagestan (Russia) at a height of 1750 m above sea level were extracted using supercritical CO 2
extraction. The extraction was carried out at a constant temperature of
311 K and pressure values of 8, 10, 15, 20, 25, and 30 MPa. The
extract, which was obtained at 10 MPa, was analyzed by gas
chromatography coupled with mass spectrometry. As a result of the
analysis, 44 compounds were revealed, with 43 of these being identified.
In the extract, the major components were α-pinene (7.11%), sabinene
(19.47%), β-myrcene (11.97%), limonene (2.64%), β-elemene (2.31%),
germacrene-D (20.66%), germacrene-D-4-ol (4.90%), bisabolol (2.78%), and
linoleic acid (5.28%). © 2013 Pleiades Publishing, Ltd.
