摘　　要：目的研究甘草根中Cu、Fe、Mn、Ca、Mg、Zn6种元素的次级形态。方法按照元素次级分析流程,分别用732阳离子交换树脂、Chelex-100螯合树脂、AmberliteXAD-2型大孔吸附树脂,将甘草根中Fe、Zn、Cu、Mn、Ca、Mg分为游离态和非游离态、稳定态与不稳定态、有机态与无机态6种形态,火焰原子吸收测定各形态中各元素含量。结果甘草根中Cu、Mn、Ca、Mg4种元素主要以游离态存在,Cu、Mn、Ca、Mg、Zn稳定态含量均大于50%,且Cu、Mn、Ca、Mg、Zn元素大部分以无机态形式存在。结论甘草中上述6种元素以游离态与非游离态、稳定态与不稳定态、有机态与无机态等多种形态共存。Objective To study secondary-level speciation of Cu,Fe,Mn,Ca,Mg,Zn in roots of Glycyrrhizia uralensis Fisch..Methods The six elements Cu,Fe,Mn,Ca,Mg,Zn in the roots of manual cultured Glycyrrhizia uralensis Fisch.were extracted based on traditional secondary analytical flow chart program and separated into dissociative and non-dissociative,stable and unstable,organic and inorganic forms by means of 732 cation exchange resin,100 chelating resins and XAD-2 resins.Contents of Cu,Fe,Mn,Ca,Mg,Zn in each form was detected by flame atomic absorption sepctrophotometry（FAAS）.Results The contents of Cu、 Mn、Ca、 Mg and the contents of Cu、Mn、Ca、Mg and Zn in dissociative and stable forms were more than 50%,majority of Cu、Mn、Ca、Mg and Zn were in inorganic forms.Conclusion The second forms of Cu、Fe、Mn、Ca、Mg Zn in the roots of manual cultured Glycyrrhizia uralensis Fisch.are presented in dissociative and non-dissociative,stable and unstable,organic and inorganic forms at the same time.
