摘要(Abstract):

[Objective]To measure the heavy metals and trace elements in 11 Rhizoma chuanxiong samples collected from 5 representative producing areas and perform correlation analysis. [Methods]The contents of the heavy metals including Hg,Cd,Pb,As,Cu,Zn,Se,Mn and Fe and the trace elements in the Rhizoma chuanxiong samples tested were measured by inductively coupled plasma optical emission spectrometer( ICP-OES),then the correlation between heavy metals,trace elements and producing region was analyzed by partial least squares using software simca- P +. [Results] The regression equations for each element detected by ICP-OES all showed a good linear relationship, with the correlation coefficient between 0. 999 7- 1,and recovery of 90. 02%- 108. 02%. [Conclusions]The microwave digestion-ICP-OES established in this study is simple,efficient and accurate,and can be used for the determination of heavy metals and trace elements in Rhizoma chuanxiong. The contents of heavy metals and trace elements are to some extent correlated with producing regions,in detail,the content of Fe, Mn,Zn and Cu showed an ascending trend in traditional Rhizoma chuanxiong producing regions. To conclude,it is suggested to periodically monitor the soil condition in traditional Rhizoma chuanxiong producing regions,and the pollution of heavy metals caused by climate.
