Abstract: In order to study the relationship between trace elements of Spatholobus suberectus dunn and efficacy,and continue to develop andutilize Spatholobus suberectus dunn,ICP-MS was applied to simultaneously determine 28 elements concealed spatholobus suberectus dunn for the first time.The sample was dissolved with microwave digesting,wet digesting and dry ashing.Thematrix effect was corrected by the in-line addition of internal standard (Be,Y,Sc,In,Re).The analysis method is simple,rapid,accurate and fiting to the determination of elements in Chinese herbs.The detection limits of these element werein the range of 0.01~0.8 μg/L.The relative standards (RSD) were in the range of 0.11%~2.57%,and the recoveries were in the range of 94.00%~110.00%.The results show that large amounts of elements are embodied in spatholobus suberectus dunn.There are 13 kinds of element content in 2 mg/kg above.The contents of Ca、Kand Mg are in conformation with the medical effects of spatholobus suberectus dunn.It can provide scientific basis for further development of the effect of Spatholobus suberectus dunn.

Key words: ICP-MS, elements, Spatholobus suberectus dunn
