正交设计法优选止咳化痰合剂提取工艺

目的 优选止咳化痰合剂提取工艺。方法 采用超声浸泡—水提回流法对药材进行提取。以君药陈皮的主要活性成分橙皮苷的提取率、黄芩中主要活性成分黄芩苷的提取率以及干浸膏得率为综合考察指标,采用正交设计法考察浸泡时间、加水量、提取时间、提取次数四个因素的影响,优选最佳提取工艺,并进行工艺验证。结果 最佳工艺为加10倍药材量的水超声浸泡20min,提取2次,每次80min。结论 验证试验表明,通过正交试验优选的止咳化痰合剂提取工艺稳定可行。

Optimization of Extraction Process for Zhike Huatan Mixture by Orthogonal Design

OBJECTIVE To optimize the extraction process for Zhike Huatan mixture. METHODS Ultrasonic soakage-reflux extraction method was used for the extraction of medicinal plants. With the overall score of extraction rate of hesperidins and baicalin, and dry ointment yield rate as the observed index, orthogonal design was used to examine four factors including soaking time, additive water amount, reflux time and extraction times in order to optimize the extraction process. And then process certification was carried out. RESULTS The optimum extraction process was as follows:add 10 times amount of water to soak the medicine plants for 20 min using ultrasonic method, then reflux twice, 80 min for each. CONCLUSION The experimental results showed that the extraction process of Zhike Huatan mixture was stable and feasible by orthogonal test.
