摘　　要：目的:建立和完善贵州民族药桤木质量标准,为桤木质量控制及合理开发利用提供科学的依据和参考。方法:研究建立薄层色谱法用于桤木的定性鉴别、采用HPLC法建立指纹图谱,多指标综合评价桤木质量。结果:桤木薄层色谱鉴别方法操作简单、专属性强、斑点清晰;建立桤木指纹图谱,有15个共有特征峰,并用对照品指认其中2个色谱峰,同时不同采集点的桤木指纹图谱相似度≥0.985。结论:本研究可为桤木质量标准提升提供参考。Objective:To establish and improve the quality standard of Guizhou ethnic medicine Alnus cremastogyne,and provide scientific evidence and reference for the quality control and rational development and utilization of Alnus cremastogyne.Methods:Thin layer chromatography was developed for the qualitative identification of Alnus cremastogyne,HPLC method was used to establish fingerprint,and multi-index comprehensive evaluation of Alnus cremastogyne quality.Results:The thin layer chromatography identification method of Alnus cremastogyne was simple,specific and clear.There were 15 common characteristic peaks,and two of them were identified by reference substances.At the same time,the similarities of fingerprints of Alnus cremastogyne at different collection sites were≥0.985.Conclusion:This study can provide reference for improving the quality standard of Alnus cremastogyne.
