摘要: 建立苍耳草药材中无机元素的电感耦合等离子体质谱﹙ICP-MS﹚分析方法,测定苍耳草不同产地及商品药材12个样品中24种无机元素的含量,用SPSS16.0对数据进行主成分分析及相关性分析。检测结果显示苍耳草药材中24种元素之间有一定的相关性,Ca、K、Mg、P、Fe的含量较高,重金属及有害元素的含量应引起重视;主成分分析选出5个主因子,得出Ca、K、Sr、Fe、Al、V、Mg、Ba、Mn是苍耳草的特征无机元素。本实验为苍耳草药材的质量控制及安全性评价提供依据。

Abstract: The aim of this study was to establish an inductively coupled plasma-mass spectrometry(ICP-MS) method for the simultaneous analysis of inorganic elements in Xanthii Herba from different areas and commercial resources.The quantitative analysis of 24 inorganic elements in 12 samples were detected.They were used for cluster and principal component analysis by SPSS16.0.The results showed that the contents of Ca,K,Mg,P,Fe were high,the heavy metals and harmful elements should be cause for concern.Five principal components were selected by principal component analysis and Ca,K,Sr,Fe,Al,V,Mg,Ba,Mn were determined to be the characteristic inorganic elements.The results of this experiment provided the basis for quality control and safety evaluation of Xanthii Herba.

Key words: Xanthii Herba, producing area, commercial herb, inorganic element, ICP-MS
