    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、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

1.提取:多用乙醇或丙酮等提取后,再用极性较小的溶剂如:乙醚、氯仿等进行萃取。2.分离:色谱法、溶剂萃取法、分级沉淀法、重结晶法.第四章醌类化合物【一】醌类的提取1.有机溶剂提取法(甲醇、乙醇-氯仿、苯-两相水解)2.碱提酸沉法 (带游离羟基或羧基)3.水蒸汽蒸馏法(分子量小的苯醌及萘醌类)4.超临界提取法【二】醌类化合物的分离1.游离蒽醌衍生物与蒽醌苷类的分离溶剂法-酸化2.游离蒽醌苷元pH梯度萃取法:原理:酸性不同方法:用pH不同的碱性水溶液萃取碱性由小到大结果:提取物按酸性由大到小被分离文档编码:CR6N5B4D9C3 HT7P2B3U6E9 ZV1O4A6J9A8文档编码:CR6N5B4D9C3
