FIELD : medicine; food industry.SUBSTANCE : invention relates to nanotechnology, medicine and food industry. Method of producing nanocapsules of a dry extract of propolis is characterized by that a dry extract of propolis is added to a suspension of sodium alginate in isopropanol in presence of 0.01 g of glycerol ester with one or two molecules of edible fatty acids and one or two molecules of citric acid as a surfactant while stirring 1000 rpm, then butyl chloride is added, the obtained suspension of nanocapsules is filtered and dried at room temperature, wherein the weight ratio of core : shell is 1 : 1, 1 : 2 or 1 : 3.EFFECT : what is disclosed is a method for producing nanocapsules of dry extract of propolis.1 cl, 3 ex
