| Abstract: | [Objective]The aim was to determine the content of seven trace elements(Cr,Ag,Zn,Ni,Cd,Fe,Cu) in Prunella vulgaris root.[Method]The sample was digested with ashing method and determined by flame atomic absorption spectrometry(FAAS).[Result]The contents of trace elements Cr,Zn,Ni,Cd,Fe and Cu in P.vulgaris root were as follow:1.416,1.064,4.880,0.010,4.992,12.936 μg/g,except Ag was undetected.The sequence of tested trace element contents was Cu,Fe,Ni>Cr>Zn>Cd.The recovery rate was between 98.6% and 116.7%.[Conclusion]The contents of Cu,Fe,Ni in the P.vulgaris root were abundant. |
