FIELD: medicine.
SUBSTANCE: ethylic dihydroquercetin consisting of mixed bioflavonoids, is pre-heated, passed through a baromembrane filter and through a coal absorptive layer with electrochemical potential, watered and exposed to recrystallisation. After watering, a filtrate is cooled to +10°C÷12°C and passed through the magnetic field generated by the same constant magnet poles, and when passing through the baromembrane filter, the solution is exposed to the polarising field. When passing through the coal absorptive layer, the solution is exposed to the low-voltage and low-current DC electric field, and the filtrate is diluted with deionised water in the ratio 1:2. The product is crystallised under vacuum at temperature below -20°C. 3. A device for dihydroquercetin purification includes a feed pump and a heater of ethylic dihydroquercetin, the baromembrane filter, the coal absorptive layer, a water feeder and a crystalliser.
EFFECT: invention allows for higher product yield.
