多指标综合评分法优选柴芍肠宁颗粒的提取工艺

目的:采用多指标综合评分法优选柴芍肠宁颗粒的提取工艺,为该制剂的生产工艺提供技术参数。方法:采用正交试验法,以出膏率和芍药苷、盐酸小檗碱、柠檬酸提取量为定量指标,小鼠小肠推进率、小鼠腹泻指数为药理指标,考察溶剂用量、提取时间、提取次数对提取效果的影响,通过综合评分法优选柴芍肠宁颗粒的提取工艺。结果:乌梅单煎的最优提取工艺条件为加10倍量水提取2次,每次1 h;柠檬酸提取量154.17 mg·g~(-1),出膏率31.27%。其余药味的最佳提取工艺条件为加10倍量水提取3次,每次1 h;芍药苷、盐酸小檗碱提取量分别为3.97,0.66 mg·g~(-1),出膏率26.36%,小肠推进率61.97%,腹泻指数0.98。结论:该提取工艺设计合理、稳定可行,对柴芍肠宁颗粒的生产工艺制定具有一定的指导意义。

Optimization of Extraction Technology of Chaishao Changning Granules by Multi-index Comprehensive Evaluation Method

Objective: To optimize extraction process of Chaishao Changning granules. Method: Orthogonal design were used to optimize extraction process of Chaishao Changning granules by taking solvent volume,extraction time and times as factors,composite score among yield of dry extract,contents of paeoniflorin,berberine hrdrochloride and citric acid,intestinal propulsive rate and diarrhea index was index. Result: Optimum extraction process of Mume Fructus was:extracted twice with 10 times the amounts of water,1 h for per time;extracting amount of citric acid was 154.17 mg·g^-1,yield of dry extract was 31.27%.Optimum extraction process of others herbs in Chaishao Changning granules was:extracted thrice with 10 times the amount of water,1 h for each time;extracting amounts of paeoniflorin and berberine hydrochloride were 3.97,0.66 mg·g^-1,yield of dry extract was 26.36%,intestinal propulsive rate was 61.97%and diarrhea index was 0.98. Conclusion: These optimized processes are stable and feasible,which can provide reliable reference value for the actual production of Chaishao Changning granules.
