摘要：采用ICP-MS测定红芪不同部位中13种无机元素含量,并对其进行单因素方差分析、聚类分析、相关性及因子分析,分析不同部位红芪中13种无机元素的分布规律。发现红芪不同部位含有丰富的无机元素,不同部位As、Pb含量无显著性差异(P>0.05),B、Hg、Be、Al、Ti、V、Ga、Ba、Ce、Sr、Mo含量具显著性差异(P<0.05),13种无机元素含量在红芪不同部位中存在极大值与极小值;元素含量之间存在显著的或极显著的正(负)相关关系;13种无机元素将红芪不同部位分为两类,根、叶及果实聚为第一类(Ⅰ类),茎、花聚为第二类(Ⅱ);Ba、Mo、Al元素是红芪不同部位的特征性元素。表明不同部位对不同元素的吸收具有一定的选择性,不同部位的无机元素之间存在相互作用。
The contents of 13 inorganic elements in different parts of Hedysari Radix were determined by ICP-MS. The distribution of the 13 inorganic elements in different samples was analyzed by one-way ANOVA, cluster analysis, correla- tion analysis and factor analysis. The results found that different parts of Hedysari Radix contained abundant inorganic elements, and the contents of As, Pb in different parts had no significant difference （ P 〉 0.05 ）, but the contents of B, Hg, Be, A1, Ti, V, Ga, Ba, Ce, Sr, Mo had significant difference （ P 〈 0.05 ）. There were maximum and minimum values for the content of 13 inorganic elements in different parts of Hedysari Radix and a significant positive or negative correla- tion existed between the contents of elements. Different parts of Hedysari Radix can be divided into two categories, by these 13 inorganic elements. Among them, roots, leaves and fruits clustered into the first group （I）, stems and flowers clustered into the second group （II）. Ba, Mo and A1 were the characteristic elements of different samples. The results showed that different parts of Hedysari Radix had a certain selectivity in absorption of different elements, and the con- tents of inorganic elements in different parts existed correlations.
