【摘要】 人参二醇类皂苷经酶转化等方法处理,得到Rh2和Rh3为主的混合物。经常压硅胶柱分离,得到纯Rh2,也得到Rh3粗品;Rh3粗品再经高压硅胶柱分离,成功地得到了Rh3单体。其纯度达到95%以上。更多还原

【Abstract】 The compound of rare ginsenoside Rh₂ and Rh₃ are obtained by enzyme hydrolysis from proropanaxtiol saponins.Ginsenoside of pure Rh₂ and crude Rh₃ are separated by ordinary silica gel column gradient elution.The Rh₃ monomer is further achieved by high-pressure silica gel column separation,with the purity over 95%.更多还原
