摘　　要：目的:建立白花丹中微量元素的测定方法。方法:采用电感耦合等离子体发射光谱(ICP-AES)法同时测定白花丹中Cu、Zn、Fe、Ca、Mg、Mn、Sr等7种微量元素,原子荧光(AFS)法测定Se元素。结果:2种方法的RSD在0.78%～3.01%之间(n=5),元素回收率在91.9%～105.8%之间,测定结果较理想。白花丹中含有非常丰富的Se元素,Cu、Zn、Fe、Ca、Mg、Mn、Sr等元素也较为丰富。结论:本方法简便、快速、准确,适于分析测定白花丹中的微量元素,测定结果对研究白花丹的药理作用具有参考意义。OBJECTIVE： To establish a determination method for trace elements of Plumbago zeylanica. METHODS： Inductively coupled plasma emission spectrum （ICP-AES） was used to determine seven trace elements of P. zeylanica, i.e. Cu, Zn,Fe, Ca, Mg, Mn and Sr simultaneously. Se was determined by atomic fluorescence （AFS） method. RESULTS： The RSD ranged from 0.78% to 3.01% （n=5）, while the recovery was within 91.9% -105.8%. The result obtained was satisfactory. Se took a large proportion in P zeylanica, followed by Cu, Zn, Fe, Ca, Mg, Mn, Sr.CONCLUSION： The method is brief, rapid and accurate for the determination of P.. zeylanica. The study provide reference for future pharmacological study of P zeylanica.
