建立了电感耦合等离子体质谱法(ICP-MS)测定不同采收期山楂叶中微量元素的半定量分析模式.结果表明,不同采收期山楂叶可测定的28种微量元素中,Mg、Si、K、ca、Na、Al、Mn、Fe、Sr和Ba为主要元素.Zn、Rb、Sc、Li、Ge、In和Bi的含量随叶的生长逐渐下降,而Zr、Sn、sb和,Th与之相反,其它元素基本没有变化.该法简单、选择性强、灵敏度高、定量准确,适用于不同采收期山楂叶中微量元素测定,为全面控制山楂叶质量提供依据,也为合理开发和利用山楂叶提供借鉴.

To establish an inductively coupled plasma mass spectrometry (ICP - MS) method for determining the trace elements for the Hawthom leaves in different collecting time. The results indicated that Mg, Si, K, Ca, Na, Al, Mn, Fe, Sr and Ba were the main trace elements in Hawthorn leaves, Zn, Rb, Sc, Li, Ge, In and Bi decreased, oppositely, Zr, Sn, Sb and Th increased, and others were not remarkably changed. The method was simple with high selectivity, sensitivity and accuracy, which was applicable to the determination of trace elements and can be as the index of reasonably utilizing and exploiting the Hawthom leaves.
