摘　　要：目的:对甘肃陇西黄芪中的5种重金属(Pb、Cd、Cu、As、Hg)含量进行测定。方法:采用湿法消解对样品进行处理,通过原子吸收(AAS)法对重金属含量进行测定。结果:甘肃陇西不同地区黄芪中的重金属含量均不超标。结论:AAS法能准确测定黄芪中重金属的含量。OBJECTIVE：To determine the content of 5 kinds of heavy metal elements in Astragalus membranaceus from Longxi of Gansu province,i.e. Pb,Cd,Cu,As,Hg. METHODS：Wet digestion pretreatment was carried out for samples and atomic absorption spectrometry （AAS） was used for the determination of heavy metal elements. RESULTS：The contents of 5 kinds of heavy metal elements in A. membranaceus from Longxi of Gansu Province were lower than the limit. CONCLUSION：AAS method can accurately determine the content of heavy metal elements in A. membranaceus.
