Black cumin volatile oil is one of the richest sources of TQ, in savory, TQ is a minor component. Volatile compounds in extracts were determined by GC-MS and GC-FID. The composition is strongly influenced by extraction pressure and modifier content in CO2. The highest concentration of TQ in savory extracts (1.5 wt.%) was obtained at 28 MPa, 50°C, 4.7 wt.% of acetone. In case of black cumin, the use of mild conditions (12 MPa, 50°C, 0 wt. % acetone) allowed separation of the volatile oil from fatty oil. Concentration of 20 wt.% of TQ was reached using 3.7g CO2/g seeds.
