FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing nanocapsules of betulin. Said method is characterised by dispersing betulin powder in sodium alginate suspension in benzene in presence of glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid while mixing at 1,300 rpm, further, flushing butyl chloride, obtained suspension of nanocapsules is filtered and dried at room temperature, wherein weight ratio of core/cladding in nanocapsules is 1:3 or 1:1.
EFFECT: invention simplifies and speeds up process of producing betulin nanocapsules and increases mass output.
