The present study was aimed to compare different mathematical models used to simulate process of supercritical extraction from commercially important Lamiaceae herbs. Supercritical extractions with carbon dioxide from rosemary, sage, thyme and lavender originated from the southern Balkan region were performed at 10 MPa and 40°C. Obtained extraction curves were simulated by the model based on the heat transfer analogy, Sovova's model and the model on the micro‐scale. The models were used to analyse mass transfer phenomena and to quantify mass transfer parameters in the fluid and/or solid phase as well as the solubility of the solute in supercritical phase.
