METHOD FOR OBTAINING NANOCAPSULES OF QUERCETIN OR DIHYDROQUERCETIN IN GELLAN GUM Russian patent published in 2016 - IPC A61K31/352 A61K9/51 A61K47/36 A61J3/07 B82B3/00

Abstract RU 2573978 C1

FIELD: chemistry.

SUBSTANCE: quercetin or dihydroquercetin is added to suspension of gellan gum in hexane in presence of glycerol ester with one-two molecules of food fatty acids and one-two molecules of citric acid, after that butylchloride is added by pouring, obtained suspension of nanocapules is filtered and dried, with ratio core/envelope in nanocapsules constituting 1:3.

EFFECT: simplification and acceleration of process of obtaining quercetin and dihydroquercetin nanocapsules, increase of output by weight.
