Analysis on the Content and Variation Trends of Metalic Elements in Eucommia ulmoides Oliv. Samples from Different Areas

Qingsong Li

Abstract

The content of metalic elements,including Fe,Cu,Mg,Ca,Mn,Zn,in Eucommia ulmoides Oliv leaves(EU leaves)from different areas was determined by flame atomic absorption spectroscopy and the variation trends were analyzed.The results showed that the EU leaves are full of metalic elements which necessary for people.There were significant differences among different origin samples in metallic elements.Fe,Zn,Mn and Mg content difference is remarkable,while Cu and Ca content difference is non-significant,and that the changing trends of Zn,Mn and Mg in the leaves of EU leaves from different areas are similar.
