Abstract: 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.
