Key words: supercritical extraction, essential oil, Satureja hortensis L., gcms, component content
A comparative estimation of the component composition of supercritical carbon dioxide (SC-CO2) extracts obtained at different thermodynamic parameters and the essential oil of Satureja hortensis L. reveals the differences in the content of separate components. It is determined that the CK-CO2 extract yield at 30 MPa (3.718 %) is more 2 times higher than at 10 MPa (1.792 %) and the essential oil content (1.75 %). The main components are а-Thujene, Myrcene, а-Terpinene, ï-Cymene, У-Terpinene, Thymoquinone, Thymol, Carvacrol, (E)-Caryophyllene, 3-Bisabolene, n-Hexadecanoicacid, methyllinolenate, n-Triacontane. Besides the aforesaid substances,in the extract obtained at 30 MPa and 50 °C there are found 3-cis-Terpineol, Neophytadiene, Hexadecanoicacid, Linoleic, methyllinolenate, n-Pentacosane, n-Hexacosane, n-Nonacosane and Squalene.
