FIELD: chemistry; biochemistry.
SUBSTANCE: invention relates to biotechnology and a method of obtaining an extract which contains salicylate from crushed air-dried bark of willow tree or twigs of willow tree with leaves. The method involves treatment of the raw material with a buffer solution of potassium phosphate with simultaneous addition of an enzymic complex in amount of 0.1% of the mass of the plant material, where the enzymic complex contains cellulose and β-glucanase enzymes, with subsequent inactivation of enzymes at 100±5°C for 10 minutes, filtration of the extract, centrifuging, evaporation and drying.
EFFECT: invention intensifies the process of extracting phenol compounds from plant material while preserving biological value of the extract.
