目的:优选小青龙贴膏的乙醇渗漉提取工艺条件。方法:以盐酸麻黄碱和芍药苷提取量为考察指标,用高效液相色谱法测定其含量,采用正交试验设计对提取条件优选。结果:优选工艺为:以55%乙醇浸泡时间12 h后渗漉,溶剂用量10倍,渗漉速度30 mL.min-1.kg-1。结论:优选工艺所得盐酸麻黄碱和芍药苷含量较高,工艺稳定可行。
Objective: To optimize the extraction process of ethanol extract from Xiaoqinglong paste. Methods: Taking the extraction of ephedrine hydrochloride and paeoniflorin as indexes, the content of ephedrine hydrochloride and paeoniflorin were determined by high performance liquid chromatography (HPLC). The orthogonal design was used to optimize the extraction conditions. Results: The optimum conditions were: percolation with 55% ethanol for 12 h, solvent 10 times, percolation rate 30 mL.min-1.kg-1. Conclusion: The higher content of ephedrine hydrochloride and paeoniflorin obtained by the process is stable and feasible.
