摘 要：
[目的]确定三七茎基总皂苷含量测定方法,优化其回流提取工艺。[方法]采用香草醛-高氯酸法测定三七茎基总皂苷含量的方法,并以总皂苷含量为指标,优选回流法提取三七茎基总皂苷的工艺条件。[结果]在0.008 3～0.049 6 mg/ml浓度范围内,人参皂苷Rg1浓度与吸光度的线性关系良好(R=0.999 4),平均回收率为99.3%(n=4),RSD为3.4%。最佳提取工艺条件为:料液比1∶10(g/ml)、乙醇浓度60%,浸泡时间12 h,提取3次,每次2 h。[结论]该含量测定方法简便、准确、重现性好;提取工艺经济、合理,值得进一步推广。

摘 要：
[Objective] To optimize the methods for content determination and backflow extraction technology of total saponins in stem base of Panax notoginseng(Burk) F.H..[Method] The content of total saponins was determined by the methods of vanillin-perchloric acid and the extraction technology was optimized by the content of total saponins.[Result] Panax saponin Rg1 presented good linear relationship over the range of 0.008 3 to 0.049 6 mg/ml(r=0.999 4).The average recovery was 98.6% with the RSD of 3.54%(n=4) respectively.The optimal solvent backflow extraction conditions were as follows:P.notoginseng stem base was soaked for 12 h in 60% ethanol at the solid-liquid ratio of 1∶ 10 g/ml and extracted for 3 times for 2 h each time.[Conclusion] This method is simple and feasible,highly accurate and precise.The extraction process is economical,reasonable and deserved popularizing all the more.
