不同产地炒牛蒡子饮片中24种无机元素的ICP-MS分析

ICP-MS analysis of 24 kinds of inorganic elements in processed Fructus Arctii from different habitats

目的测定不同产地炒牛蒡子饮片中无机元素的含量。方法样品经微波消解后,采用ICP-MS法测定无机元素的含量,用SPSS 23.0对数据进行主成分分析、相关性分析。结果检测了炒牛蒡子饮片24种元素,元素之间有一定的相关性,K,P,Mg,Al,Na,Fe的含量较高,重金属及有害元素的含量在限量标准之内;主成分分析选出2个主因子,显示Al,V,Si,Ti,Fe,Mn,Ni,Cr,Co,Pb,Li,P,Mg,Mo,Sr,Cd是炒牛蒡子饮片的特征无机元素。结论该研究为炒牛蒡子饮片的质量控制及安全性评价提供了依据。

Objective To determine the contents of the inorganic elements in processed Fructus Arctii from different habitats.Methods The sample solutions were analyzed by ICP-MS after microwave digestion. The data of principal components,correlations were analyzed with the SPSS 23. 0 software. Results Twenty four inorganic elements in processed Fructus Arctii were determined. There were some correlations among the inorganic elements in processed Fructus Arctii. The contents of K,P,Mg,Al,Na and Fe were abundant. The content of heavy metals and harmful elements are within the limits. Two main factors were selected PCA,which showed that Al,V,Si,Ti,Fe,Mn,Ni,Cr,Co,Pb,Li,P,Mg,Mo,Sr and Cd may be the characteristic elements in processed Fructus Arctii. Conclusion This experiment provides the evidence for the quality control and safety evaluation of processed Fructus Arctii.
