METHOD FOR PRODUCING NANOCAPULES OF BETULIN IN GELLAN GUM Russian patent published in 2017 - IPC A61K31/56 A61K47/36 A61K9/51 A61J3/07 B82B3/00

Abstract RU 2622750 C1

FIELD: nanotechnology.

SUBSTANCE: method is characterized in that 100 mg of betulin powder is slowly added to a suspension of 100 mg or 300 mg of gellan gum in butanol in the presence of 0.01 g of E472c with stirring at 1300 rpm, then 3 ml of hexane are added, the resulting suspension is filtered and dried at room temperature.

EFFECT: simplification and acceleration of betulin nanocapsule production, weight yield increase.
