摘　　要：建立电感耦合等离子体发射光谱法(ICP-OES)测定12个不同产地细辛药材根中Mg、Ni、Na、K、Ca、Ba、Mo、Mn、Cr、Fe、Cu、Li、Zn、Co、V、Cd、As、Pb 18种元素含量的测定方法。样品粉碎成粉末状经HNO3-HClO4(4∶1,V/V)湿法消解处理后测定。结果表明,该方法相关系数均大于或等于0.9991,回收率在95.0%—105.0%之间,相对标准偏差均不大于4.91%。本法快速,灵敏、准确,可用于质量控制,为不同产地的细辛药材中元素的含量测定提供了方法。The ICP-OES method was established to determine 18 elements（Mg,Ni,Na,K,Ca,Ba,Mo,Mn,Cr,Fe,Cu,Li,Zn,Co,V,Cd,As and Pb） in roots of Asarum from 12 different producing areas.The concentrations of the 18 elements in roots of Asarum were measured after digestion samples powder with violet acid HNO3-HClO4（4/1,V/V）.The correlative coefficient of the calibration curves was greater than 0.9991.The recoveries of all the elements tested were between 95.0%—105.0%,while the RSDs were less than or equal to 4.91%.This method is brief,rapid and accurate,which can be used for the quality control of elements in roots of Asarum from different habits.
