摘　　要：In the study, the contents of 5 trace elements including Fe, Cu, Mg, Mn and Ca were directly analyzed by flame atomic absorption spectroscopy in Gu- oshangye. The sample was subjected to microwave digestion with HNO3 and H2O2, and detected by the standard curve method. The results showed that Guoshangye contained abundant trace elements which rates of these trace elements were in the curacy and satisfactory. were necessary for human. The recovery range of 96%-103%. The method is ac-[目的]测定黔产果上叶中5种金属元素的含量。[方法]运用火焰原子吸收光谱法测定果上叶中Fe、Cu、Mg、Mn和Ca 5种金属元素,采用浓硝酸-双氧水微波消解样品,标准曲线法检测回收率。[结果]所测定的果上叶中含有丰富的人体必须金属元素,回收率在96%~103%。[结论]该方法准确易行,结果令人满意。
