Abstract：The contents of trace elements Zn,Cu,Mn and Fe in 20 kinds of benefit traditional Chinese medicines were determined by FAAS. The recovery rates obtained by standard addition method is between 96.8％ and 104.3％,and the RSD is lower than 2.0%. The results of the determination show that benefit traditional Chinese medicines are rich in trace elements such as Zn,Cu,Mn and Fe. Hematonic has the highest content of Fe. The content of Zn,Mn and Fe is relatively high in Qi-invigorating drugs. The content of Zn and Mn is relatively high in maletonic,while Yin-nourishing drugs have lower content of Fe. The results will provide scientific data for the study on the elements in benefit traditional Chinese medicines and on their relativity of efficacy of medicine.
