微波消解-ICP-OES法测定小叶榕药材中微量元素

Determination of Trace Elements in Ficus microcarpa by ICP-OEC

【目的】建立一种小叶榕(Ficus microcarpa)药材中微量元素的测定方法。【方法】采用微波消解样品,电感耦合等离子体质谱法(ICP-OES)测定小叶榕药材中12种微量元素的含量。【结果】电感耦合等离子体质谱法测定药材中微量元素的含量线性好、操作简便、快速准确、灵敏度高。小叶榕药材中含量丰富的微量元素,从高到低依次为Mg、Fe、Al、Mn、Zn等。【结论】建立了微波消解-ICP-OES测定小叶榕药材中多种微量元素的分析方法。

Objective]A method was established to determine the trace elements in Ficus microcarpa.[Methods]ICP-OES was used to determine the content of 12 trace elements in Ficus microcarpa sample digested by microwave.[Results]Different kinds of trace elements were found in Ficus microcarpa and their richness listed in order were Mg,Al,Fe,Mn and Zn.The method of ICP-OES showed good linearity,high recovery and high accuracy.[Con-clusion]Different kinds of trace elements have been found in the Ficus microcarpa,which is determined by ICP-OES.
