摘　　要：火焰原子吸收光谱法（ FAAS）分别测定绿茄、紫茄不同部位中Fe、 Cu、 Mn三种微量元素的含量。结果：绿茄、紫茄不同部位中均含有上述三种微量元素，且含量存在差异，其中绿茄、紫茄各部位含量大小均为： Fe＞Mn＞Cu，其中铁在两种茄子的皮、蒂部位中无显著差别，绿茄子肉中的铁含量高于紫茄子肉中的含量，在绿茄、紫茄相同部位中，绿茄子的锰元素含量较多；该实验的回收率在91.80％～105.30％之间， RSD＜1.60％，结果令人满意。The green tomato, Fe, Cu, Mn in different parts of the content of three kinds of trace elements were determined with flame atomic absorption spectrometry （ FAAS）.The results showed green , purple tomato and tomato were found in different parts of the above three kinds of trace elements , and had differences content , in which each part of the green eggplant , purple tomato amount were Fe 〉Mn 〉Cu, including iron in two eggplant skin and the place of no significant difference , the iron content of green eggplant meat was above the eggplant content in flesh , in green tomato, in the same place , the manganese content of green eggplant was more.The experiment of recovery rate was between 91.80%-105.30%, RSD〈1.60%, and the result was satisfactory.
