摘　　要：采用微波消解法处理样品,以电感耦合等离子体原子发射光谱法(ICP-AES)测定新疆洋葱籽样品中Co、Cr、Ca、K、Mg、P、Fe、Mn、Na、Ni、Sn、Zn、Cd、As、Se、Cu、Mo和V 18种常量/微量元素。结果显示,新疆洋葱籽中含有丰富的K、Mg、P、Ca和Na等常量元素,此外微量元素Fe、Mn、Zn、Cr、Ni、Cu的含量也较丰富。新疆洋葱籽中含有很多对人体有益的常量及微量元素,有较高的药用价值。Six samples were pretreated by microwave digestion method and analyzed by inductively coupled plasma atomic emission spectrometry（ICP-AES）. And 18 kinds of major/trace elements in Xinjiang Alliurn cepa L. seeds were determined including Co, Cr, Ca, K, Mg, P, Fe, Mn, Na, Ni, Sn, Zn, Cd,As,Se, Cu, Mo and V. Results indicated that Allium cepa L. seeds were riched in major elements such as K, Mg, P, Ca and Na, besides, the trace elements Fe, Mn, Zn, Cr, Ni, and Cu were also relatively abundant. Allium cepa L. seeds contain a lot of major and trace elements which are beneficial to human body and have high medicinal value.
