摘 要：
采用ICP-AES法测定决明子(Cassia obtusifolia L.)中Na、Mg、P、Ca、Ti、Zn、Mn、Fe、K、Sr、B、Al、Ba,采用ICP-MS法测定Li、Be、Tl、Mo、Pb、Cd、Co、V、Cr、Cu、Ni。结果表明,决明子中富含K、Ca、P、Mg、Al、Fe、Na,而Be、Cd、Tl、Pb等元素含量极微,不足0.02μg/g。在所测定的24种元素中,含量顺序依次为K>Ca>P>Mg>Al>Fe>Na>Zn>Sr>B>Mn>Ba>Cu>Ti>Cr>Ni>Mo>Co>V>Li>Cd>Pb>Tl>Be。

摘 要：
The content of Na,Mg,P,Ca,Ti,Zn,Mn,Fe,K,Sr,B,Al,Ba in Cassia obtusifolia L.was determined by ICP-AES while of Li,Be,Tl,Mo,Pb,Cd,Co,V,Cr,Cu,Ni was determined by ICP-MS technique.The results indicated that the content of K,Ca,P,Mg,Al,Fe,Na was high in C.obtusifolia L..However,the content of Be,Cd,Tl and Pb in samples was low,all less than 0.02 μg/g.The content of 24 elements renked as K>Ca>P>Mg>Al>Fe>Na>Zn>Sr>B>Mn>Ba>Cu>Ti>Cr>Ni>Mo>Co>V>Li>Cd>Pb>Tl>Be.
