FIELD: chemistry.
SUBSTANCE: invention refers to a method for producing a colouring agent of mulberry fruit applicable in medicine, pharmaceutical industry, particularly in staining histologic specimen and dosage forms. The method involves drying a substrate in vacuum in a foam layer at a heat flux of E=1.5-3.0 kW/m2, a biomaterial layer thickness of 2-5 mm and a residual pressure in a vacuum enclosure of 7 kPa. The dry substrate is extracted for 24-34 hours in a solution of tartaric acid and ethanol in a weight ratio of 2-8:18-24 at a room temperature.
EFFECT: invention provides simplifying the process due to preventing heating in extraction, using easily acceptable extractants and reducing their amount in increasing tinctorial properties of the colouring agent.
