METHOD OF PRODUCING NANOCAPSULES OF GREEN TEA EXTRACT Russian patent published in 2016 - IPC A61K9/50 A61K47/38 A61K36/82 A61J3/07 B82B3/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to a method of producing nanocapsules and describes a method of producing nanocapsules of green tea extract. Method is characterised by using sodium carboxymethylcellulose as a shell and green tea extract - as a core; during the method implementation green tea extract is added to the suspension of sodium carboxymethylcellulose in butanol in presence of E472c surfactant, herewith the ratio of core:shell in terms of recalculation to dry substance is 1:1 or 1:3, or 1:5, then while stirring methylene chloride is added and the obtained suspension is filtered and dried at room temperature.

EFFECT: method provides simplifying and accelerating the process of nanoencapsulation, while reducing accompanying loss.
