摘　　要：采用微波消解电感耦合等离子体-原子发射光谱法测定了苋菜中的矿质元素Ca、Cd、Cr、Cu、K、Fe、Mg、Mn、Na和Zn的含量,分析结果的相对标准偏差为0.12%—5.72%。该方法简单、快速、可靠、灵敏度高,且多元素可以同时测定,能满足实际样品分析需要。实验表明,苋菜中含有丰富的矿质元素,尤其是Ca、K、Mg含量较高,显示了苋菜较高的营养价值。The ten mineral contents of Ca,Cd,Cr,Cu,Fe,K,Mg,Mn,Na and Zn in Amaranthus mangostanus L.were determined by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.The relative standard deviations for all these elements in this method were between 0.12% and 5.72%.The measuring method was proved to be simple,rapid,reliable,and highly sensitive.In addition,the determination of these mineral elements can be carried out at the same time,which can meet the requests of actual sample analysis.The experimental results show that Amaranthus mangostanus L.contains plentiful mineral elements,especially Ca,K,Mg,which imply that the nutritive value is high.
