Abstract. Supercritical carbon dioxide fluid extraction is widely used to obtain lipid substances from essential oil raw materials. The study has demonstrated the feasibility of using supercritical extraction to isolate substances exhibiting various biological activities from coriander (Coriandrum sativum) fruits. Extraction has been carried out at a pressure of 10 and 20 MPa; in receiving separators 1 and 2, the pressure varies from 4 to 6 MPa; the temperature in the working column is maintained at 35 °C; gas flow rate is 2.1 l/min. The total yield of the lipophilic fraction is 10.8 %, with the maximum yield observed in separator 2. The yield at 10 MPa reaches 4.88 %, and at 20 MPa – 5.92 %. Gas chromatography-mass spectrometry has been performed for two fractions obtained as a result of extraction. The content (as a percentage of the total amount of all components) of the main target component varies in the range of 39.04–75.9 %; fatty acids – 43.3 % (fraction 1) and 14.1 % (fraction 2). The study has included a solubility test of the obtained samples, verification of the obtained results, and a comparative analysis of the effectiveness of the presented method relative to standard extraction methods and raw material preparation. The obtained results demonstrate the potential of fluid extraction for obtaining coriander essential oil.
