采用Ni（NO3）2－Mg（NO3）2溶液作为混合基体改进剂，微波消解－石墨炉原子吸收光谱法测定了五种彝族植物药中硒的含量。结果表明：五种样品中硒含量在0．0959μg? g－1和1．411μg? g－1之间。且该方法的标准曲线线性关系良好（ R＝0．9989），回收率为95．1％～101．3％， RSD值（ n＝8）为3．73％～7．56％。所建方法简便、快速、准确、可靠，可用于彝药中硒的含量测定。
採用Ni（NO3）2－Mg（NO3）2溶液作為混閤基體改進劑，微波消解－石墨爐原子吸收光譜法測定瞭五種彝族植物藥中硒的含量。結果錶明：五種樣品中硒含量在0．0959μg? g－1和1．411μg? g－1之間。且該方法的標準麯線線性關繫良好（ R＝0．9989），迴收率為95．1％～101．3％， RSD值（ n＝8）為3．73％～7．56％。所建方法簡便、快速、準確、可靠，可用于彝藥中硒的含量測定。
