FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing nanocapsules. Disclosed a method for nanocapsules of tetracycline family antibiotics, such as tetracycline, doxycicline or minocycline. Carrageenan is used as nanocapsule shell material. According to the method antibiotic was added to the suspension of carrageenan in petroleum ether with E472c present, followed by benzene, and the resulting suspension of nanocapsules was filtered, washed and dried. The core : shell ratio in the nanocapsules was 1:1, or 1:3, or 1:5 or 5:1.
EFFECT: quick and simple process of nanocapsule production, reduced process losses (increase of mass yield).
