摘要目的 优选复方肤清洗剂的提取工艺.方法 采用Plackett-Burman试验设计法和正交试验相结合的方法,研究水提取复方肤清洗剂的影响因素;用HPLC梯度洗脱法同时测定复方肤清洗剂中绿原酸、芍药苷、咖啡酸含量;以多指标综合评分法进行数据分析,优选工艺条件.结果 复方肤清洗剂提取的最佳条件为:过80目筛,浸泡2 h,加12倍量水,回流提取3次,每次1 h.结论 该提取工艺合理、稳定,可用于复方肤清洗剂中药材的提取.

abstractsObjective To optimize extraction technology of Fufang-Fuqing-Xiji.Methods Orthogonal test combined with Plackett-Burman experimental design was adopted to study the influence factors of water extraction in Fufang-Fuqing-Xiji. The contents of chlorogenic acid, paeoniflorin and caffeic acid in Fufang-Fuqing-Xiji were determined by HPLC gradient elution method at the same time. A multi-index comprehensive score method was applied to analyze the data and to screen the optimum extraction technology. Results The best extraction conditions of Fufang-Fuqing-Xiji were as following: threaded 80 mesh sieve, soaked 2 h, decocted 3 times with 12 times the amount of water for 1h each time.Conclusions This optimized extraction technology was rational and stable, which could be used for the extraction ofFufang-Fuqing-Xiji.
