【摘要】 目的:采用星点设计-效应面法优选胃宁分散片(三七、人参)的提取工艺。方法:以乙醇量、乙醇浓度和提取时间为主要影响因素,以三七总皂苷含量和浸膏得率为评价指标,用星点设计-效应面法选择提取工艺的最佳条件。结果:最佳提取工艺为加入10倍量70%乙醇、提取2次、每次2 h。结论:用星点设计-效应面法优选胃宁分散片的提取工艺方法简便,预测性好。更多还原

【Abstract】 AIM: To optimize the extraction of Weining-Dispersible Tablet(Radix et Rhizoma notoginseng,Radix et Rhizoma ginseng) with the help of central composite design-response surface methodology. METHODS: The main influencing factors of extraction effect included the quantity of ethanol,the concentration of ethanol and extraction time and the extraction conditions were evaluated by the extract yield and the contents of total notoginseng saponins.The optimal extraction of Weining-Dispersible Tablet was selected by central composite design-response surface methodology. RESULTS: The optimal conditions consisted of extraction two times,2 h each time with ten fold of 70% ethanol. CONCLUSION: It is simple,convenient and high predictive to optimize the extraction craft of Weining-Dispersible Tablet by central composite design-response surface methodology.更多还原
