Studies on Improving Control Standard of Wan Bi Qing Pill

摘要:

目的: 提高顽痹清丸的质量标准体系。 方法: 采用薄层色谱法对处方中紫草、吴茱萸、土茯苓进行定性鉴别研 究;采用高效液相色谱法对忍冬藤进行含量测定研究。 结果: 薄层色谱斑点清晰,阴性对照无干扰;马钱苷在0.013 4~0.080 4 g·L^-1呈良好的线性关系(r=0.999 8);平均加样回收率为97.07%,RSD 1.24%。 结论: 建立的薄层色谱法和高效液相色谱法专属性强、准确度高、重复性好,可用于顽痹清丸的的质量控制。

Abstract:

Objective:To improve the quality standard of Wanbiqing Pill. Method: The TLC method was used to identify Arnebiae Radix, Euodiae Fructus and Smilacis Glabrae Rhizoma. The HPLC method was used to detect the content of loganin in Lonicerae japonicae caulis. Result: This TLC method is good in separation, strong in specificity and negative in interference. Loganin was detected in the range of 0.013 4-0.080 4 g·L^-1, indicating good linear relationship (r=0.999 8). The mean sample recovery rate was 97.07% and the RSD was 1.24%. Conclusion: The TLC and HPLC methods are simple and accurate in operation, high precision and good in reproducibility, and they can be taken as the standard of quality control for Wanbiqing Pill.
