| Abstract: | The content of six trace elements in Gnaphalium affine D.Don,including Fe,Cu,Mg,Ca,Mn and Zn were analyzed by flame atomic absorption spectroscopy after diluted by microwave with HNO3.The results revealed that Gnaphalium affine contains plenty of trace elements which are necessary for body.The method is simple and rapid and the recovery of these microelements is between 98.9% and 104.0%. |
