摘　　要：采用硝酸-高氯酸法消化干姜样品,应用火焰原子吸收法测定干姜中的K、Na,Ca,Mg,Fe,Co,Ni,Cu,Zn,Mn,Cd,Cr和Pb等13种金属元素的含量。结果表明:在这13种元素中,除Cr未检出外,含量比较高的依次是K,Ca,Na,Mg,Mn,Fe,其中最高为K,达20100μg.g-1;最低为Cd,仅0.53μg.g-1。Determination of the amount of 13 metal elements of K,Na,Ca,Mg,Fe,Co,Ni,Cu,Zn,Mn,Cd,Cr and Pb in Zingiber Officinale Rosc.was studied by flame atomic absorption spectrophotometry（FAAS）after HNO3-HClO4 digestion.The analytical results indicated that there were comparatively rich elements in Zingiber Officinale Rosc.such as K,Ca,Na,Mg,Mn and Fe,especially the concentration of K in the highest,amounting to 20100 μg ·g-1,However,concentrations of Cd were very low,only 0.53 μg ·-1,while Cr were not checked out in the samples.
