Schinus terebinthifolius Raddi is a plant rich in nutrients and is used medicinally and industrially. Supercritical oil extraction from S. terebinthifolius can result in higher value-added products. Mathematical models (Sovová and Esquível) are used to describe the behavior of supercritical extractions. This study aims to compare both models in terms of yields in conditions of 223 bar and 50°C. We observed that the model proposed by Sovová provided good reproducibility and representativeness.
