摘　　要：目的:利用原子吸收光谱法测定金钱草中金属元素含量。方法:使用HNO3～HClO4体系消解样品,采用火焰原子吸收光谱法测定6种不同来源的金钱草中的Mg,Fe,Mn,Cu,Zn 5种金属元素。结果:金钱草中含有丰富的金属元素,其含量由高到低依次为Mg,Fe,Mn,Zn,Cu,加标回收率在97.11%～102.94%,相对标准偏差(n=6)在0.83%～3.37%。结论:建立了原子吸收光谱法测定金钱草中Mg,Fe,Mn,Cu和Zn元素的含量,该方法快速,简便,灵敏,结果准确可靠。Objective： To determine the contents of metal elements in Lysimachia christinae H. by FAAS. Method： The samples were digested with the HNO3-HC104 system and then the flame atomic absorption spectrometry was adopted to determine the contents of five mental elements （Fe, Mg, Mn, Cu and Zn） in L. christinae from six diferent places. Result： L. christinae contains abundant mental elements. The contents of five mental elements from high to low is Mg, Fe, Mn, Zn and Cu successively. The additional standard recoveries of samples were between 97.11% and 102.94% with RSD （ n = 6） of the range from 0.83% to 3.37%. Conclusion： The established method to determine the conetents of Mg, Fe, Mn, Cu and Zn in L. christinae was of high sensitivity, good stability, precision and accuracy.
