    • The invention relates to a method of preparation and isolation of betulin diacetate from birch bark from paper mills and its optional processing to betulin, wherein the birch bark is ground, mixed with two- to twenty-fold excess volume of water and is stirred so that all birch bark is dipped, then the fraction of the birch bark which floats on the surface is collected, said collected fraction is dried at the temperature in the range of from 50 to 85 °C and the betulin contained in the dried birch bark is then subjected to an acetylation reaction, after the acetylation the birch bark is dried at the temperature of from 50 to 100 °C and the formed betulin diacetate is then isolated from the birch bark by supercritical extraction of the birch bark with carbon dioxide at the pressure of 28-35 MPa and the temperature of from 50 to 100 °C and subsequently, the supercritical extract is recrystallized for direct use or for further processing. The further processing can be basic hydrolysis of the re-crystallized betulin diacetate to betulin.
    • 本发明涉及从造纸厂的桦树皮制备和分离桦木二乙酸酯的方法及其对桦木醇的任选加工,其中将桦树皮研磨,与二至二十倍体积的水混合并搅拌,使得 将所有桦树皮浸渍,然后收集漂浮在表面上的桦树皮部分,收集的部分在50至85℃的温度范围内干燥,然后将干燥的桦树皮中含有的桦木醇 进行乙酰化反应,乙酰化后,桦木树皮在50〜100℃的温度下干燥,然后通过超临界萃取桦树皮与二氧化碳在压力下从桦木树皮中分离形成的桦木醇二乙酸酯 28-35MPa,温度为50〜100℃,然后将超临界萃取物重结晶直接使用或进一步处理。 进一步的处理可以是重结晶的桦木醇二乙酸酯至桦木醇的碱性水解。
