Abstract
The prospects of using liquid and supercritical carbon dioxide for extracting biologically active substances (BASs) from sapropels are examined. The chemical composition of extracts was studied by high-performance liquid chromatography. Varying the parameters of extraction (temperature, pressure, and time) allows adjusting the total extract yield and the degree of extraction of various BASs.
