Composition of extract of the Juniperus oblonga M. Bieb. Fruits obtained by supercritical CO2 extraction

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%).
