FIELD: biotechnology.

SUBSTANCE: according to the invention, a method for active molecules extraction from a plant substrate comprises the step of the said substrate contacting with an extraction liquid. This extraction liquid contains: an extraction gas in the gaseous state at a temperature of 23°C and a pressure of 1 atm (101.325 kPa), and an extraction solvent in a liquid state comprising or consisting of acetic acid alone or mixed with at least one of water and primary aliphatic alcohol having the formula (V) R-OH, wherein R is a C1-C10 alkyl group, preferably C1-C5, wherein the said extraction gas is selected from the group consisting of helium, neon, argon, krypton, xenon, carbon dioxide and nitrogen, or mixtures thereof; wherein the said extraction gas is introduced into the said extraction solvent at a concentration of 0.1 to 10 vol % relative to 100 parts by weight of the extraction solvent. Active molecules extraction from plant substrate. Extract application for preparation of a food composition for internal use. Extract application for preparation of a food supplement for internal use. Extract application for preparation of a nutraceutical composition for internal use. Extract application for preparation of a pharmaceutical product for external or internal use.

EFFECT: method allows to obtain an extract with a high yield of biologically active substances, to avoid chemical destruction of extracted molecules or modification of the original chemical structure.
