摘 要：目的 研究影响复方枳参胶囊提取效果的各种因素，确定最佳提取工艺。方法 采用正交试验设计，以浸膏收率和槲皮素提取率为指标，考察回流提取时间（A）、乙醇体积分数（B）、提取次数（C）和乙醇用量[乙醇体积（mL）/药材量（g），D]4个因素对提取效果的影响，优选出复方枳参胶囊的提取工艺。结果 在所考察的4个因素中，对复方枳参胶囊提取效果的影响程度依次为：B＞D＞C＞A，即乙醇体积分数＞乙醇用量＞提取次数＞回流提取时间，确定出最佳提取工艺为 B2D3C2A3，即10倍于药材量（g）的70%乙醇（mL），回流提取2次，每次2 h 为最佳提取工艺。结论 本实验优选出的提取工艺适用于复方枳参胶囊的提取。

Abstract: Objective To determine the best extraction technique by studying the different factors that might affect the extraction of Fufang Zhishen Capsules．Methods The orthogonality experiment was adopted in the study．Extraction rate of quercetin and the extractum rate were taken as indices．The effects of four factors on the extraction were studied，including reflux extraction time（A），volume grade of alcohol（B），extraction times （C），and alcohol volume（D）which was calculated by alcohol volume（mL）divided by the amount of materials （g）．On the basis of the study on the four factors，the extraction technique was optimized．Results The effects of the four factors were listed as follows：B＞D＞C＞A．The best extraction technique was described as B2D3C2A3．The amount of 70% alcohol was 10 times of the medicinal materials．There were total 2 times of reflux extraction with 2 hour in each time．Conclusion The optimized technique is suitable to the extraction of Fufang Zhishen Capsule．
