Folium artemisiae argyi quality detection method based on HPLC fingerprint spectrum

The invention relates to a quality control method for traditional Chinese medicinal materials, in particular to a folium artemisiae argyi quality detection method based on an HPLC (High Performance Liquid Chromatography) fingerprint spectrum. According to the method, seven differential markers capable of being used for analyzing the quality of the folium artemisiae argyi are obtained through a clustering analysis method and a principal component analysis method. By utilizing the contents of the differential markers, the quality of the folium artemisiae argyi can be detected, and meanwhile, the production place of the folium artemisiae argyi can be further identified. The method disclosed by the invention is very good in specificity, precision, repeatability, stability and sample adding recovery rate, and has a very good application prospect. 本发明涉及中药材质量控制方法，具体涉及一种基于HPLC指纹图谱的艾叶质量检测方法。本发明通过聚类分析和主成分分析法获得了可用于对艾叶的质量进行分析的7种差异标志物。利用这些差异标志物的含量，能够对艾叶的质量进行检测，同时还能够进一步对艾叶的产地进行鉴别。本发明方法的专属性、精密度、重复性、稳定性和加样回收率均很好，具有很好的应用前景。
