Description	This work is focused on the enhancement of TQ concentration in volatile oil using SFE of black cumin (Nigella sativa L.) seeds and savory (Satureja hortensis L.) aerial parts. 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.
