目的:研究愈心痛胶囊的质量标准。方法:TLC法鉴别红参、三七及RP—HPLC法测定延胡索乙素的含量。含量采用Waters C18色谱柱(200 mm×4.6 mm,5μm);流动相为乙睛-0.1%三乙胺溶液(50∶50),流速1 mL.min-1;检测波长:282nm;用外标法定量。结果:阴性对照均无干扰;0.08472~2.118μg范围内有良好的线性关系(r=0.9999),平均加样回收率为98.4%(n=6)。结论:所建方法简单、可靠,可用于愈心痛胶囊的质量控制。
Objective: To study the quality standard of Yuxintong capsules. Methods: The contents of tetrahydropalmatine in Rhizoma Panoptis, Panax notoginseng and RP-HPLC were determined by TLC. The mobile phase consisted of acetonitrile-0.1% triethylamine (50:50), the flow rate was 1 mL · min-1, the detection wavelength was 282 nm, Legal quantity. Results: There was no interference in the negative control. There was a good linearity (r = 0.9999) in the range of 0.08472 ~ 2.118μg with an average recovery of 98.4% (n = 6). Conclusion: The method is simple and reliable, and can be used for the quality control of Yuxin Capsule.
