摘　　要：使用HNO3-HClO4体系消解样品,采用火焰原子吸收光谱法测定5种不同来源青蒿(Artemisia an-nua L·)中的Mg、Fe、Mn、Cu和Zn含量。结果表明,青蒿中5种金属元素的含量大小依次为Mg>Fe>Zn>Mn>Cu,该法加标回收率在98.00%～104.00%,相对标准偏差(n=3)为0.51%～2.86%。该法快速、简便、灵敏、准确,可用于青蒿中金属元素的分析。The samples were digested with the HNO3-HClO4 system and then the flame atomic absorption spectrometry was adopted to determine the contents of 5 mental elements(Fe,Mg,Mn,Cu,Zn) in Artemisia annua L.with 5 different resources.The result showed the content of 5 mental elements in A.annua L.from high to low were Mg,Fe,Mn,Zn and Cu.The additional standard recoveries of sample was 98.00%～104.00% with RSD(n=3) of 0.51%～2.86%.The established method was fast,simple,sensitive,precise and accuract.
