FIELD : nanotechnologies; medicine; food industry.SUBSTANCE : invention relates to nanotechnology, medicine and food industry. Method of obtaining nanocapsules of dry extract of elecampane is characterized by the fact that dry extract of elecampane is added to a suspension of guar gum in methanol 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 1, 000 rpm, 6 ml of petroleum ether are then poured, the resulting nanocapsule suspension is filtered and dried at room temperature, and the core : shell mass ratio is 1 : 1, 1 : 2 or 1 : 3.EFFECT : method is proposed for preparing nanocapsules of dry extract of elecampane.1 cl, 3 ex
