Objective: To explore a method for determination of trace elements in Apocynum ventum L. Methods: After Apocynum venture L.being treated by microwave-assisted sample digestion, thirteen trace elements in the sample and the standard control material were determined by Induc-tively Coupled Plasma Mass Spectrometry (ICP-MS) . Results: RSD of the method are 0.2%～5.8%, and the recovery rate are 89.3%～108.7%. The contents of Mn,Li in the sample are higher and Cr, Ni,Pb and Cu are lower. Conclusion: ICP-MS can be used to determine trace elements of Apoc-ynum ventum L.in which the contents of toxic elements are lower than that of the standard value.
