摘要：采用ICP-MS测定不同生长年限红芪中13种无机元素含量,并分析其规律,发现不同生长年限红芪样品之间As、Pb、B、Al、Ti、Ga、Ba元素含量无显著性差异(P>0.05),Hg、Be、Mo元素含量具极显著性差异(P<0.01)。V、Ce、Sr元素含量具显著性差异(P<0.05);生长年限与Hg,Mo含量之间存在极显著负相关关系,与V含量之间存在极显著的正相关关系,与B含量之间存在显著的负相关关系;生长年限与Hg含量之间存在线性回归关系,与Hg元素、V元素的含量之间存在Fisher的线性判别式函数关系,Hg、Mo、Ce、B是不同生长年限红芪特征性元素,无机元素表征了不同生长年限红芪质量的差异性。研究结果为其他豆科多年生药用植物的生长年限判别及与无机元素的关系提供参考。
To analyze the law of 13 inorganic elements of Hedysari Radix in different growth ages by ICP-MS. The result showed that the contents of As,Pb,B, Al,Ti,Ga and Ba were no significant difference （P 〉 0 . 0 5 ） ,the contents of Hg, Be and Mo were significant difference （ P 〈 0. 01） , the contents of V, Ce and Sr were obviously difference （ P 〈 0. 05 ）. The result of correlation analysis showed that growth ages of Hedysari Radix had significantly negative correlation with Hg and Mo contents and had significantly positive correlation with V contents and had significantly negative correlation with B contents. There were the linear regression relationship between the contents of inorganic elements and growth a- ges,there were the linear discriminant function of Fisher between the contents of Hg and V and growth ages. Hg,Mo,Ce and B were the characteristic trace elements of Hedysari Radix. The inorganic elements characterized the differences of the quality of samples with different growth ages. Our results provided a reference for identifying the growth ages of other leguminous medicinal plants and studying relationships with inorganic elements and growth ages.
