FIELD: medicine, pharmaceutics. ^ SUBSTANCE: invention relates to pharmaceutics and medicine. Humified material is exposed to alkaline hydrolysis in the presence of oxygen. Liquid phase is separated, acidified, produced residue is separated and washed until pH value is neutral, dried. Produced product is extracted by ester of carbonic acid, fluid extract is removed, produced residue is extracted by alkanol, alkanol is removed. Produced dry residue is purified by re-subsidence from alkaline solution with application of aqueous solution of mineral acid to produce target product. ^ EFFECT: invention makes it possible to produce highly efficient and low-toxic agent. ^ 15 cl, 1 ex |
