摘　　要：采用微波消解-火焰原子吸收光谱法测定滇重楼和华重楼中Ca、Mg、K、Fe、Zn、Cu、Mn等7种金属元素的含量。结果表明,2种药材中金属元素的含量存在差异,其中滇重楼中宏量元素Ca、K、Mg,以及微量元素Cu的含量高于华重楼;而华重楼中微量元素Fe、Zn、Mn的含量高于滇重楼。实验的相关系数r≥0.9898,测定值的RSD在0.38%—1.70%之间,方法稳定可靠,其结果为进一步开发利用重楼药材资源提供了依据。The 7 metal elements（calcium,potassium,magnesium,iron,zinc,copper and manganese）in two kinds of Rhizoma Pridis[Paris polyphylla Smith var.yunnanensis（Franch.） Hand.-Mazz.and P.polyphylla Smith var.chinensis（Franch.） Hara]were determined by FAAS with microwave digestion.The contents of macro and trace elements from the two kinds of Rhizoma Pridis were quite different.The concentrations of Ca,Mg,K and Cu in P.polyphylla Smith var.yunnanensis（Franch.） Hand.-Mazz.were higher than P.polyphylla Smith var.chinensis（Franch.） Hara.then the contents of Fe,Zn and Mn of the second one was higher than the first one.The relative coefficients were equal or greater than 0.9898,and the RSD were between 0.38% and 1.70%.The method is stable and reliable.And the experimental data provides a basis for the further development and utilization of Rhizoma Pridis resources.
