篇名: 正交试验结合综合评分法优化苗药了哥王的提取工艺
TITLE:
摘要: 目的:优化了哥王的提取工艺。方法:以了哥王的有效成分伞形花内酯、西瑞香素的含量和浸膏收率作为综合评价指标,以溶剂量、乙醇体积分数、渗漉速度为考察因素,采用单因素试验对了哥王的3种提取方法(渗漉法、煎煮法和回流提取法)进行比较,筛选最优提取方法;再用正交试验对最优提取方法的工艺条件进行优化并验证。结果:提取方法的综合评分排序为渗漉法>回流提取法>煎煮法,以渗漉法更优。渗漉法的最优工艺条件为渗漉溶剂70%乙醇,溶剂量为14 倍药材量,渗漉速度为5  mL/(min·kg);验证试验中3次试验的综合评分分别为98.3、99.3、98.8(RSD=0.51%,n=3)。结论:了哥王有效成分的提取方法选用渗漉法,优选出的渗漉法提取工艺稳定、重现性好。
ABSTRACT: OBJECTIVE: To optimize the extraction technology of Wikstroemia indica. METHODS: Using the active ingredient contents of umbelliferone and daphnoretin, and extraction yield as comprehensive evaluation indexes, solvent dosage, ethanol volume fraction, percolation rate as investigation factors, single factor test was conducted to compare the 3 extraction methods (percolation method, boiling method, reflux extraction method), and screen the optimized one; and the technology conditions of optimized method were optimized and verified. RESULTS: The comprehensive score ordered as percolation method, reflux extraction method, boiling method, which was better by percolation method. The optimal technology conditions was as follow as percolation solvent of 70% ethanol, 14-fold herbs at percolation rate of 5 mL/(min·kg); the comprehensive scores in 3 tests were 98.3, 99.3, 98.8 (RSD=0.51%, n=3). CONCLUSIONS: Percolation method is optimized for extracting active ingredient of W. indica, which is stable and reproducible.
