摘要

【摘要】目的探讨牛蒡子、威灵仙提取的优化条件。方法以牛蒡子苷含量、齐墩果酸含量为指标，确定乙醇浓度（％）、乙醇用量、提取时间为影响因素，并以L9( )正交实验表安排实验。结果牛蒡子、威灵仙最优工艺为：提取两次，每次用60%乙醇，10倍量，提取1.5小时。结论优选的提取条件效率高，可增加药材的利用率。

Abstract

ABSTRACT Objective To optimize the extraction process of Fructus Arctii and Radix Clematidis. Methods Using orthogonal design method， to apply extract yield of Fructus Arctii and Radix Clematidis and the extract amount of arctiin and oleanolic acid as observing indexes. Results The optimum extraction process was as follows

adding 10 times of 60％alcohol into coptis meal

refluxing and extracting for 2 times

half and an hour every time. Conclusion This optimized process is simple

stable and efficient.
