It was presented the one- step method of extraction high purity of betulin 97,7%. Betulin identified using of physicochemical methods: elemental analysis, IR and NMR spectroscopy, electron scanning microscopy, studied the thermal characteristics of betulin. It is shown that betulin exhibits gastroprotective, hepatoprotective and capillaries strengthening properties. Keywords: birch bark, betulin, sodium hydroxide, potassium hydroxide, gastroprotective, hepatoprotective, capillaries strengthening properties. References 1. Kislitsin A.N.
