摘　　要：目的研究不同产地菊花中微量元素的含量及其分布特征。方法采用电感耦合等离子体发射光谱法(ICP-OES)测定6种菊花中13种微量元素的含量,应用主成分分析法,结合SPSS19.0版软件进行元素特征分析。结果不同产地菊花的微量元素含量的曲线具有一定的相似性,其中铁(Fe)、锌(Zn)、锰(Mn)等元素的含量比较高;主成分分析的结果表明6种菊花有5个主成分因子,其特征微量元素为镉(Cd)、铜(Cu)、锌(Zn)、钡(Ba)、钴(Co)。结论各种微量元素的含量和分布特征能反映不同产地菊花的特性,对菊花的质量评价及分类有参考价值。Objective To study the contents and distribution characteristics of trace elements in Chrysanthemum morifolium from different areas. Methods The contents of 13 trace elements in six samples of Chrysanthemum morifolium were determined by ICP-OES.The principal component analysis combined with SPSS 19.0 software was applied to evaluate charac- teristics of elements Results Curves of trace element content of Chrysanthemum morifolium from different origins had a certain similarity.The contents of Fe, Zn and Mn were higher than others.The results of principal component analysis showed that five principal components were extracted from six samples of Chrysanthemum morifolium, and Cd, Cu, Zn, Ba and Co was the characteristic trace elements. Conclusion The contents and distribution of trace elements can reflect the characteristics of Chrysanthemum morifolium from different areas, which could be used for Chrysanthemum morifolium quality assessment and classification.
