Abstract: Sorbus aucuparia meal, a bioactive product and a waste product of pharmaceutical production, contains biologically active substances, including lipids that cannot be extracted with ethanol in primary production.Supercritical carbon dioxide is a good extractor for such compounds.Optimization of the extraction of Sorbus aucuparia oil from processed berries was carried out using a full factorial experimental method using a single design by supercritical fluid extraction with carbon dioxide.Ultrasound was used in the extraction process, and ultrasound with a frequency of 50 kHz was found to be optimal for the process.The main parameters of the design were selected as pressure of 250 atm, temperature of 60 °C, and hydromodule of 25.To increase the accuracy of the optimization, the coefficients were sequentially introduced based on the Fisher criterion.Analysis of the regression equation allowed us to determine the optimal parameters of the process: temperature 60-70 °C, pressure 250-350 atm, hydromodule 33, oil yield 1.4-1.5%.The relative error of the model was 1%.The results of the experiment conducted based on the proposed technique and technology are presented in tabular and graphical form
