FIELD OF THE INVENTION The invention relates to food and pharmaceutical industry.

There is a method of extracting biologically active substances from plant raw materials by extracting the latter with a mixture of low-melting fraction of mink oil, Eb / o ethyl alcohol and freon 113. Extraction is carried out in two stages, and in the first stage they are extracted with alcohol and freon, in the second stage they are added low-melting fraction of mink fat and continue extraction with increasing temperature to 55 ° C (1).

The disadvantage of this method is the incomplete extraction of biologically active substances.

The purpose of the invention is to increase the yield of the target product.

This goal is achieved according to the method of extraction of biologically active fat-soluble substances from vegetable raw materials by treating with ethyl alcohol and freon, then a low-melting fraction of mink oil during heating, filtering, before filtration, glycerol is introduced in an amount of 3-5% / o with a residual pressure of 100- 150 mmHg Art.

Example. Chopped vegetable raw materials with moisture (herbs are Hypericia.

chamomile and others) with a particle size not exceeding 8 mm, it is poured with 96% ethyl alcohol and freon 113 and infused for 4 hours, then a low melting fraction of mink oil is introduced with stirring for U5 hours. At the end, the temperature is raised to 55 ° - 5 ° C and maintain it for 24 hours with continuous stirring. The ratio in a mixture of solvent: low fraction of mink fat 85-93 / o, ethyl alcohol 960 / o-tion and freon 113-2-3%, and the ratio of raw materials and solvent is 1:10. Then, the extracted mass is cooled to 20 ° + 5 ° C and under vacuum with a residual pressure of 100-150 mm Hg. Art. 3–5% glycerol by weight is introduced and fed to an ioutch filter, where a layer of residue remains on the filter, which is washed with pure alcohol to fully extract biologically active substances and is used further for the next batch of vegetable raw materials. The isolated filtrate extract is clarified and the yield of the final product is determined from the difference between the initial weight of the loaded plant material, solvent and glycerin.

As can be seen from the Dani in the table, the proposed method allows an increase in the yield of the extract by 5-10%.
