提高芦丁提取效率的优化设计

目的筛选出对芦丁提取具有较好协同作用的非离子型表面活性剂，优化卢丁提取工艺。方法考察常见非离子型表面活性荆对卢丁提取效率的影响，以筛选出的提取效率较好的非离子型表面活性剂作为协同剌．采用L9（3^4）正交试验。对影响槐花米提取效果的诸因素（药材的粉碎度、表面活性剂用量、溶剂用量、加热时间）进行优选。结果Tween-20对芦丁的提取具有明显协同作用。药材粉碎度和表面活性剂用量为显著性影响因子。其他两个因素虽有影响，但均为非显著性影响因子。结论在本实验条件下芦丁的最佳提取工艺条件为：药材用量10g、药材为细粉、Tweerl-20周量0．05g、溶剂200ml、提取时间30min。

Orthogonal test for the study of the effects on the extraction efficiency of rutin from flos sophorae and for the optimization of extraction process

Objective To select the most efficient surfactant for extracting rutin from Flos sophorae and optimize the extraction process.Methods Different non-ionic surfactants were used as assistants to extract rutin from flos sophorae under the same conditions and the most efficient surfactant for extracting rutin from Flos sophorae were selected.Then the L9(34) orthogonal test was used to optimize the extraction conditions.Moreover,the effects of the following conditions: the crush herbs,surfactant concentration,so...
