FIELD: pharmaceutics.
SUBSTANCE: invention relates to chemical-pharmaceutical industry and relates to a method of producing 3-acetate-28-phthalate betulinol – a biologically active substance exhibiting hepatoprotective, antifungal and anti-cystic activity. In the method described, 3-acetate-28-phthalate of betulinol is obtained by fusion of 3-acetate of betulinol with phthalic acid at ratio of reagents of 1.0:1.5 at temperature of 180–200 °C for 2–3 minutes.
EFFECT: simple process of producing betulinol 3-acetate-28-phthalate, high economic efficiency thereof by cutting the duration of the process and avoiding the use of expensive and toxic reagents.
