摘　　要：以微波消解ICP-MS/ICP-AES法测定广藿香中Mg、Al、P、Ca、Pb、Cd、Cr、Cu等24种元素,结果表明广藿香中含有较丰富的人体必需的宏量与微量元素,其中Al、Fe、K、Ca、Mg含量较高,而Tl、Mo、Be、Cd含量较少,在所检的24种元素中,Al含量最高,达38300μg/g,其次为Fe达14000μg/g,Tl、Mo、Be、Cd含量较低,均低于1μg/g。Mg,Al,P,Ca,Pb,Cd,Cr,Cu ect.24 elements were determined by ICP-MS and ICP-AES with microwave digestion.The results showed that the contents of 24 elements contain were rich in Al,Fe,K,vCa and Mg.However the contents of Tl,Mo,Be,Cd in samples were low,and the content of Al was in highest,amounting to 38300 μg/g,followed by Fe（14000 μg/g）,and the contents of Tl,Mo,Be,Cd were both less than 1 μg/g.
