FIELD: chemistry.
SUBSTANCE: invention relates to a method of extracting xanthophylls from plant material, involving extraction of xanthophylls, where the plant material is first dried and crushed and extraction is carried out in n-hexane or petroleum ether at room temperature. The extract is separated and sorbed with silica gel, after which silica gel with xanthophylls is separated from the solution and solvent residue is removed. As a rule, silica gel on which xanthophylls are sorbed is transferred into any plant oil and desorption is carried out while stirring the mixture until decolouration of silica gel. The present invention can be used to produce different plant oils rich in xanthophyll ethers or to produce biologically active additives in form of oil solutions which are excellent preventive agents against retinopathy.
EFFECT: method enables efficient and fast extraction of desired products of high quality.
