Objective To determine the contents of the trace elements in the Setcreasea purpurea. Methods The sample was digested by HNO3 . Five trace elements including Fe,Zn,Mg,Ca and Mn in the samples were directly analyzed by flame atomic absorption spectrometry. Results It was showed that the content of Mg in the sample was the highest,followed by Ca,Fe,Mn and Zn. In addition,the recoveries of these microelements were ranged from 97. 50% to 104. 15%,and the RSD was less than 2%. Conclusion As one of the traditional chinese medicine,Setcreasea purpurea contains reasonable percentage of the trace elements,which could be the reference to its qualification study. The method is simple,accurate,reliable and reproducible.
