摘    要:运用ICP—AES法对河南、新疆产猫爪草中常量及微量元素进行了测定。结果表明猫爪草含K,Fe,Ca,Cr,Mg,Mn,Zn,Co,Cu,Ni,Se,Sr等多种常量及微量元素,微量元素Pb,Cd,As等的含量甚微;研究发现猫爪草块根中Zn/Cu值为3左右,与抗癌中药中微量元素的含量有Zn高Cu低的现象一致。

关 键 词:ICP-AES法  猫爪草  常量  测定  中微量元素  Zn  Cu  含量

Abstract:The determination of twenty one kinds of constant and trace elements in Chinese herb Ranunculus ternatus thunb was performed by ICP-AES. The results show that K, Fe, Ca, Cr, Mg, Mn, Zn, Co, Cu, Ni, Se and Sr are relatively rich in Ranunculus ternatus and the content of Pb, Cd and As are very low. The ratio of the content of Zn to that of Cu is about 3, which is consistent with the relative content level of Zn and Cu contained in many anticancer Chinese traditional plants.
Keywords:Ranunculus ternatus thunb  ICP-AES  Constant and trace elements
