FIELD: chemistry.
SUBSTANCE: invention can be used to separate organic substances from aqueous media, water-containing biological fluids and aqueous extracts. The method is carried out by extracting organic substances from an aqueous medium in an organic solvent coupled with freezing in centrifugal force field conditions. An extract of the desired organic substances is obtained by adding to a suitable organic solvent to a sample, including a water-soluble or partially water-soluble solvent, which is extracted into the separated liquid phase when freezing the aqueous part in centrifuging conditions.
EFFECT: method improves reproducibility of extraction results with respect to the amount of the obtained extract, reduces the amount of the extraction agent in the extraction system and reduces water content in the obtained extract.
