FIELD : nanotechnology.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 guar gum in butanol in presence of 0.01?g of glycerol ester with one or two edible fatty acid molecules and one or two citric acid molecules as a surfactant with stirring at 1000?rpm, acetone is then added, the obtained suspension of nanocapsules is filtered and dried at room temperature, wherein the weight ratio of core to shell is 1 : 1, 1 : 2 or 1 : 3.EFFECT : method of producing nanocapsules of propolis dry extract is disclosed.1 cl, 3 ex
