FIELD: chemistry.
SUBSTANCE: invention concerns essential-oil industry. Method of obtaining oakmoss extract involves raw material grinding, extraction by ethyl alcohol, miscella sedimentation and filtration, concentration. Exhaustive extraction by hexane is performed before extraction by ethyl alcohol. Extraction by ethyl alcohol is performed by single sedimentation for 5 hours at boiling point of ethyl alcohol. After filtration processed material undergoes double or triple washing by ethyl alcohol.
EFFECT: deep selective extraction of lichen acid complex.
