Optimal selection of abstraction procedure for Xinshu Granula by orthogonal test
-
摘要: 目的 优选心舒颗粒中的醇溶性成分的提取工艺。 方法 以干膏得率、丹参酮ⅡA含量为评价指标,选用L9(34)正交表进行实验。考察提取时间、提取次数、乙醇浓度、乙醇用量对干膏得率和丹参酮ⅡA含量的影响,以多指标综合评分法确定最佳工艺。 结果 确定加生药材10倍量的90%乙醇,回流1.5 h,提取2次为最佳方案。 结论 最佳工艺基本稳定可行。Abstract: Objective To study the alcohol-soluble component abstraction procedure of Xinshu Granula. Methods The optional extraction process was selected for the yields of extracts & Tanshinone ⅡA by using L9(34) orthogonal design.The effects of alcohol concentration,alcohol amount,reflux time and times of reflux were observed. Results The optimal extraction process was determined by adding 90% alcohol,10 times the amount of Chinese medicinal materials,reflux extracting 2 times,1.5 hours per time. Conclusions The selected processing method was stable and feasible.
