| 摘 要： | 银杏内酯A、B、C及白果内酯(文中简称GA、GB、GC和BB)分子极性依次增强。因此,不同极性的有机溶剂对4种银杏萜内酯有不同的选择溶解性。通过丙酮,乙酸乙酯与乙醇三级溶解并为每一级溶解液匹配合适的柱层析吸附剂与洗脱液,从银杏提取物中分离纯化极有药用价值的银杏萜内酯。结果表明,本方法可将银杏内酯的纯度由6%提高至80%以上,并可将它们逐一分离。

| Abstract: | Ginkgolide A,B,C and bilobalide(GA,GB,GC and BB for short) had different polarities and could be dissolved in different organic solvents.EGB was dissolved by acetone,ethyl acetate and ethyl alcohol in turn and then dealed them with column chromatography,GA,GB,GC and BB valuable in medicine could be got,which concentrations were over 80% and they could be separated one by one. |
