用均匀设计法优选跌打活血涂膜剂的提取工艺

目的：优选简便可靠的提取工艺。方法：用均匀设计法对跌打活血涂膜剂的提取工艺中乙醇浓度、回流时间、回流次数、乙醇用量、药材粒度５个因素进行优选；用紫外分光光度法测定提取液的吸收度值作为评价指标。结果：在跌打活血涂膜剂的提取工艺中采用浓度９５％乙醇，回流时间 １ｈ，回流次数４次，乙醇用量 １０倍，药材粒度 ０．２ｍｍ为最佳工艺。结论：本文建立的提取工艺方法简便、可靠。

Optimizing the Extracting Process in Diedahuoxue Film With Uniform Design

AIM:To seek a simple and reliable process for extracting effective components in Diedahuoxue film .METHODS: According to uniform design, five factors in extraction were optimized, i.e. ethanol concentration, reflux time, reflux times, ethanol volume and drug particle.The absorption value was taken as evaluating parameter in UV ?spectrophotometry .RESU-LTS: The results showed that the best extracting conditions were 95% ethanol, ten times amount of ethanol, 0.2mm size of particle and reflux time of Ih with 4 repetitions.CONCLUSION:This process is simple and reliable.
