摘要
Abstract
[Objective] To determine the contents of 4 trace elements in Eucommia ulmoides Oliv.. [ Method] 4 trace elements including Zn, Cu, Ca and Mg in leaves and barks of Eucommia ulmoides Oliv. Were determined by combining microwave-assisted sample digestion with flame atomic absorption spectrometry. [Results] The recovery rates of 4 trace elements ranged from 97% to 100.9% with all RSD value being less than 3.5%. There were significant differences in contents of Zn, Cu, Ca and Mg and antihypertensive effects between barks and leaves of Eucommia ulmoides Oliv.. [Conclusion] The method was accurate,fast and convenient.关键词
