| Abstract: | ICP-MS with microwave digestion technique was used to measure the content of Li, B, Mg, V, Mn, Cu, As, Sr, Mo, Cs, Ba, Pb, Cr, Fe, Ni, Co, Sn, Sb, Bi and Cd in the roots, stems and leaves of Evodia lepta （ Spreng. ） Merr. The results showed the detection limits of all elements were 0.007 - 0. 883 mg · L- 1, the RSDs were 0.19% -3.8% ,and the recovery rate were 81.1% - 115.1%. The roots, stems and leaves of Evodia lepta （Spreng.） Merr contained Mg, Mn, Fe, B, Cu, Sr, Ni, Ba, which have some medicinal value. The method was simple, rapid, accurate, and reliable. |
