METHOD OF SEPARATING BIOLOGICALLY ACTIVE COMPOUNDS FROM PROPOLIS BY VACUUM ULTRASONIC EXTRACTION Russian patent published in 2015 - IPC A61K35/64 B01D11/02 B01D15/00

Abstract RU 2552291 C2

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.
