FIELD: nanotechnologies.
SUBSTANCE: invention relates to nanotechnology, medicine and food industry, in particular to a method for producing nanocapsules of dry extract of Hypericum. Method of obtaining nanocapsules of dry extract of Hypericum is proposed in which sodium alginate is used as a shell of nanocapsules, and dry extract of Hypericum as a core, while dry extract of Hypericum is added to suspension of sodium alginate in toluene in the presence of 0.01 g of E472c as a surfactant with stirring at 1,000 rpm, 6 ml of freon 112 are then poured, 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: described method allows to simplify and speed up the process of obtaining nanocapsules, to increase the yield by weight.
