Journal: Khimiia rastitel'nogo syr'ia (Chemistry of plant raw material)
Languages: Russian
Types: Article
Subjects: birch bark, betulin, sodium hydroxide, potassium hydroxide, gastroprotective, hepatoprotective, capillaries strengthening properties, береста коры берёзы, бетулин, гидроксид натрия, гидроксид калия, гастропротекторные, гепатопротекторные, капилляроукрепляющие свойства
It was extracted the products with yield about 40% by mas. of absolutely dry birch bark and the content in which 74 to 75% and 85-89% in the presence of sodium and potassium hydroxide, respectively. 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.
