METHOD OF RAPID PURIFICATION OF DIHYDROQUERCETIN FROM POLYMERIC FORMS Russian patent published in 2009 - IPC A61K31/351 C07D311/32

Abstract RU 2372080 C1

FIELD: chemistry.

SUBSTANCE: invention relates to engineering and purification of vegetable bioflavonoids. A solution of dihydroquercetin is passed through filters with diametre of not less than 10 cm with pore size from 0.05 to 0.45 microns at 75 to 150 Pa pressure with subsequent concentration of the filtered solution and regeneration of the filters by passing 0.1N hydrochloric acid in reverse direction.

EFFECT: invention realises said function.
