Key words: Juniperus oblonga, supercritical extraction, gas chromatography-mass spectrometry, component analysis
The extraction of Juniperus oblonga M. Bieb. fruits,growing in Dagestan (Russia) in a height of 1750 m above sea level, was obtained by means of supercritical CO2 extraction. The extraction was carried out at constant temperature 311 K and pressures 8, 10, 15, 20, 25, and 30 MPa. Using the gas chromatography/mass spectrometry analysis, 43 compounds in the extract obtained at 10 MPa are identified. Among them the major components are: 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 %), linoleic acid (5,28 %).
