1、天然药物化学提取分离总结第一章总论提取分离的基础，必须看PPT。第二章糖和苷特性：水乙醇低极性有机溶剂提取方法单糖易溶溶难容或不溶醇提酮沉低聚糖溶溶难容或不溶醇提酮沉多糖溶热水成胶体不溶难容或不溶水提醇沉苷溶溶不溶醇提酮沉苷元不溶溶溶醇提水沉粘液质树胶溶热水不溶难溶或不溶水提醇沉半纤维素只溶于碱液纤维素各溶剂均难溶红色字体为PPT上的标注。蓝色字体为根据总论得出。得到原生苷方法：采集原料时速加热干燥或冷冻保存然后热水提取或者醇提取（抑制酶解）得到次生苷、苷元方法：水提取，让酶水解糖苷，而且降低极性，便于分离（皂苷、强心苷）PPT例子：【一】溶剂抽提法（溶解度）目的：1、去杂质（多为油脂类）2、

2、分离 苷元、单糖苷或少糖苷、“多糖”苷。流程：【二】溶剂沉淀法（溶解度）目的：分离多糖（分量子不同且溶解性不同的各类多糖）文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V2P4I3Z8文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V2P4I3Z8文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V2P4I3Z8文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V2P4I3Z8文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V2P4I3Z8文档编码:CV2M3V5X9J5 HW3Q1D1R10A4 ZH1V
