FIELD: biologically active substances.
SUBSTANCE: invention is related to a method for producing betulin 3-acetate-28-maleate, a biologically active substance exhibiting hepatoprotective, antifungal and anti-yeast activity. Betulin 3-acetate-28-maleate is prepared by fusing betulin 3-acetate with maleic acid at a reagent ratio of 1.0:1.5-2.0, at a temperature of 190-200°C for 5-7 minutes.
EFFECT: new method for production of betulin 3-acetate-28-maleate has been developed, which simplifies the process, increases its efficiency by reducing the duration of the process and eliminating the use of expensive and toxic reagents.
