摘 要 目的:建立香附药材中无机元素的含量测定方法,并比较不同产地香附中14种无机元素的含量,为该药材质量控制和优
质资源开发提供理论基础。方法:采用微波消解法对样品进行处理,再采用电感耦合等离子体质谱(ICP-MS)法测定香附药材中
Na、Mg、K、Ca、Mn、Fe、Ni、Cu、Zn、As、Se、Sr、Cd、Pb的含量,运用SPSS 23.0软件对数据进行主成分分析和聚类分析。结果:不同
产地香附药材中上述14种无机元素的平均含量依次为168.62、753.71、6 938.33、24.31、14.69、197.77、0.60、2.43、26.89、0.21、0.06、
5.64、0.05、0.32 mg/kg。主成分分析结果显示,前4个主成分的累计方差贡献率为86.203%,可以反映原始数据的大部分信息;山
东、江西、山西、湖北、云南所产香附的无机元素含量综合得分排在前5位。聚类分析结果显示,9个产地样品共聚为5类,呈现出
按产区聚类的特点;从无机元素角度分析,华东、华中、华北、西南产区香附的质量优于华南产区样品。结论:香附药材中富含Na、
Mg、K、Ca、Mn、Fe、Cu、Zn、Sr等人体必需元素,含有少量Ni、As、Se、Cd、Pb元素;不同产地香附药材无机元素的含量差异与所在地
理片区具有相关性。

ABSTRACT OBJECTIVE:To establish the method for the content determination of inorganic elements in Cyperus rotundus,and
to compare the contents of 14 kinds of inorganic elements in C. rotundus from different producing areas,and to provide theoretical
basis for its quality control and high quality resources development. METHODS:The samples were processed by microwave
digestion,and ICP-MS method was used to determine the contents of Na,Mg,K,Ca,Mn,Fe,Ni,Cu,Zn,As,Se,Sr,Cd
and Pb. SPSS 23.0 software were used for principal component analysis (PCA) and cluster analysis. RESULTS:The average
contents of above 14 kinds of inorganic elements in C. rotundus from different producing areas were 168.62,753.71, 6
938.33,24.31,14.69,197.77,0.60,2.43,26.89,0.21,0.06,5.64,0.05,0.32 mg/kg,respectively. The results of PCA showed
that the cumulative variance contribution rate of the first four principal components was 86.203%,which could reflect most of the
information of the original data. C. rotundus from Shandong,Jiangxi,Shanxi,Hubei and Yunnan ranked the top five places in
terms of comprehensive score of inorganic element contents. The results of cluster analysis showed that the samples from 9
producing areas were clustered into 5 categories,showing the characteristics of clustering by producing area. From the perspective
of inorganic elements,the quality of C. rotundus from East China,Central China,North China and Southwest China was better
than that from South China. CONCLUSIONS:Essential trace elements like Na,Mg,K,Ca,Mn,Fe,Cu,Zn,Sr are rich in C.
rotundus,and there are small amounts of Ni,As,Se,Cd,Pb elements in it. The contents difference of inorganic elements in C.
rotundus from different origins may related to the geographical area it belongs to.
