Abstract The objective in this paper was to determine the amount of metal elements in the Plant Bupleurum scorzonerifolium Willd. by flame atomic absorption spectrophotometry(FAAS). FAAS method was established for the determination of Ca, Mg, Fe, Cu, Zn and Pb in the Plant Bupleurum scorzonerifolium Willd. after digestion with HNO3-HClO4(V∶V=4∶1) at 90-95 ℃ and at normal pressure. In the meantime, the optimum parameters of FAAS and the effects of solution medium on the results were studied. The analytical results of Ca, Mg, Fe, Cu and Zn were 5 588.9, 1 790.5, 869.3, 78.4, 44.3 μg·g-1 respectively, and Pb was not checked out in the samples. The results showed that the recovery of standard addition was 99.57%-102.10%, the relative standard deviation (n=9) was 0.18%-2.26%. The method is quick, simple and convenient，and the results are satisfactory.
