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.
