METHOD OF SEPARATING BIOLOGICALLY ACTIVE COMPOUNDS FROM PROPOLIS BY VACUUM ULTRASONIC EXTRACTION

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of producing dry propolis. Said method includes grinding raw material, extraction with 96% ethyl alcohol at temperature of +20-25°C using a vacuum-ultrasonic device, filtering, purification from heavy metals and other impurities using a carbon sorbent, followed by evaporation.;EFFECT: disclosed method increases output of biologically active substances and enables purification of propolis from wax, mechanical impurities, high-molecular weight substances, heavy metals and pesticides.;2 dwg, 3 tbl, 1 ex
