FIELD: chemistry.
SUBSTANCE: to obtain silicone extracts, plant material is crushed and degassed under a vacuum at temperature 35-45°C. Treatment of the material with liquid silicone as a solvent, holding, filtration and pressing are carried out in two steps to obtain lipophilic and hydrophilic biologically active substances. At the first step after degassing, the crushed material is mixed with cyclopentasiloxane, the vacuum is released to atmospheric pressure and the material is held while stirring and then further crushed. At the second step, the obtained extraction cake is held under a vacuum at temperature 35-45°C, and dimethicone copolyol is used as silicone.
EFFECT: improved method.
