摘　　要：用灰化溶解法处理试样制备测试液,用电感耦合等离子体原子发射光谱法(ICP-AES法)同时测定不同月份香椿不同部位中的Fe、Mn、Cu、Zn、Ca、Mg、Na、K、Al、Pb、Cd、和Ni12种元素的含量。该法的加标回收率在93.6%～109.0%之间,相对标准偏差RSD0.51%～4.87%,具有良好的准确度和精密度。试验结果表明:香椿中含有丰富的Ca、Mg、Fe、Zn和K等元素,Na、Mn、Cu的含量也较丰富,各元素含量随时间及部位而变化。本研究结果为香椿资源的综合利用提供科学依据。A method for the simultaneous determination of micro elements Fe、Mn、Cu、Zn、Ca、Mg、Na、K、Al、Pb、Cd、 and Ni in Toona sinensis （A Juss.） Roem in different months and different parts by ICP-AES after the sample dissolved by aching method was studied.The recoveries obtained by standard addition method were between 93.6%% and 109.0%,while the RSD （n=6） was in the range of 0.54%～4.87%,the method had a good accuracy and precision.Experimental results showed that Toona sinensis （A Juss.） Roem was rich in Ca,Mg,Fe,Zn and K,its Na,Mn and Cu content was also relatively rich,and the elements content changed with months and parts in plants.The results provided a scientific basis for the comprehensive utilization about Toona sinensis （A Juss.） Roem.
