FIELD : nanotechnologies; medicine; food industry.SUBSTANCE : invention relates to nanotechnology, medicine and food industry. Method of producing nano capsules of dry extract of burdock is characterized by that dry extract of burdock is added to a suspension of kappa-carrageenan in hexane in presence of 0.01 g of glycerol ester with one or two molecules of food fatty acids and one or two molecules of citric acid as surface-active substances while stirring at 700 rpm, chloroform is then poured in, the resulting nanocapsule suspension is filtered off and dried at room temperature, and the core : shell mass ratio is 1 : 1, 1 : 2 or 1 : 3.EFFECT : disclosed is a method of producing nanocapsules of dry extract of burdock.1 cl, 3 ex
