摘　　要：采用微波一火焰原子吸收法测定马兰中微量元素Fe，Mg，K，Ca，Zn，Na的质量分数，该方法快速、简单、准确，回收率在96．31％～104．89％之间，相对标准偏差RSD〈2．15％．结果表明，马兰中Ca，Mg，K元素的质量分数较高，具有很好的营养价值和较高的食用价值．同时也为马兰的进一步研究和深加工利用提供了新的科学依据．Seven kinds microelement such as Fe, Mg, K, Ca, Zn, Na in Kalimerisindica have been detected and analyzed by flame atomic absorption spectrophotometry. The recovery of standard addition was 96.31%～104.89%, and the relative standard deviation RSD〈2.15%. The result showed that Ca, Mg and K have a high percent in Kalimerisindica which has rich value of nutrition and medical health. In addition, supplies the new science accrowdance for the further reseach and second machining.
