摘要
目的 :研究赤芍总甙的制备工艺和质量标准。方法 :赤芍经乙醇回流 ,乙醚脂和正丁醇萃取得到赤芍总甙 ,得率 >5 % ,所得赤芍总甙以双波长薄层扫描测定了芍药甙含量 ,测定波长λS=2 5 4nm。结果 :样品中芍药甙含量平均为 44.1%。结论 :该提取方法简便、快速、可行。
Objective: To study the preparing technology of total saponins of Radix Paeoniae Rubra and its quality standards. Methods: Total saponins were extracted from Paeonia lactiflora Pall. by EtOH refluxing, EtO degreasing and n BuOH extracts, the yield was more than 5%. The dual wavelength TLC scanning was used to determine the content of paeoniflorin at 254 nm. Results: The average content of paeoniflorin in the extractive was 44.1%. Conclusion: The extracting method was simple, rapid and available.
