摘　　要：[目的]测定微量元素在蒙自喜树叶和籽中的含量。[方法]通过干法制备蒙自喜树的叶和籽样品,采用原子吸收光谱法连续测定其中Se、Mn、Hg、Fe、Pb、Zn、Cr、Cu、Cd等9种微量元素含量。[结果]试验结果表明,9种微量元素在喜树叶中的含量顺序为:Mn>Se>Fe>Hg>Zn>Pb>Cu>Cr>Cd,在喜树籽中的含量顺序是:Se>Mn>Hg>Fe>Pb>Zn>Cr>Cu>Cd。[结论]为进一步研究金属离子对喜树碱含量的影响奠定了一定的基础。[Objective]The aim of the research was to determinate the trace element content of Camptotheca acuminata Decne seed and leaf in Mengzi.[Method]Samples of Camptotheca acuminata Decne seed and leaf in Mengzi was prepared with dry process. Continuous determination of Se,Mn,Hg,Fe,Pb,Zn,Cr,Cu,Cd content was carried out with atomic absorption spectrometry.[Result] The sequence of nine trace element content in Camptotheca acuminata Decne leaf was Mn〉Se〉Fe〉Hg〉Zn〉Pb〉Cu〉Cr〉Cd,and in Camptotheca acuminata Decne seed,it was Se〉Mn〉Hg〉Fe〉Pb〉Zn〉Cr〉Cu〉Cd.[Conclusion] The experiment laid the foundations for further study of the effects on camptothecin content of metal ions.
