目的:研究岩白菜药材的质量标准,为新版《中国药典》提供可参考的数据资料。方法:采用2005年版《中国药典》一部附录方法进行薄层色谱鉴别,建立岩白菜药材中岩白菜素HPLC的含量测定方法。结果:薄层色谱鉴别专属性强,重复性好。在选定的高效液相色谱条件下岩白菜素同其他成分达到较好的基线分离,平均回收率为100.03%,RSD为0.56%,规定药材岩白菜素的含量不得低于8.2%。结论:实验方法简单、快速、可靠,能有效鉴别和评价岩白菜药材的质量。
Objective: To study the quality standards of Chinese cabbage herbs and provide reference data for the new edition of Chinese Pharmacopoeia. Methods: The method of HPLC was identified by TLC using an appendix of 2005 edition of “Chinese Pharmacopoeia”. Results: Thin layer chromatography identification of strong specificity, good repeatability. Under selected HPLC conditions, bergein achieved good baseline separation with other components with an average recovery of 100.03% and a RSD of 0.56%, providing that the content of bergenin should not be less than 8.2%. Conclusion: The experimental method is simple, rapid and reliable, and can effectively identify and evaluate the quality of Chinese cabbage.
