Abstract:Concentration of trace elements and heavy metals is an important aspect to appraise the quality of Chinese traditional medicine. Seven kinds of trace elements and five kinds of heavy metals in spaceflight achyranthes were analyzed by the method of ICP-MS. The results showed that spaceflight achyranthes contained many wholesome elements, such as Ca, Fe, Zn, Mn, Cu, Se and Mo, whose concentrations are 9 182.252 μg·g-1·DW,310.5 μg·g-1·DW,24.718 μg·g-1·DW,18 416.97 ng·g-1·DW,5 518.97 ng·g-1·DW,1 747.692 ng·g-1·DW and 211.87 ng·g-1·DW respectively. But the content of heavy metals is also high, as the concentrations of As,Pb,Hg,Cd and Cr are 514.332 ng·g-1·DW,1 657.65 ng·g-1·DW,13.212 ng·g-1·DW,49.22 ng·g-1·DW and 922.038 ng·g-1·DW respectively, which accords with the relevant standard.
