The content of Fe, Mn, Zn, Cu and Se of Ligustrum obtusiifolium fruits digested by the mixed solution of HNO_3 and HClO_4(5:1) was determined by atomic absorption spectrometry and atomic fluorescence spectrometry. The results showed that the content of Fe, Mn, Zn, Cu and Se in fruits of Ligustrum obtusiifolium was 86.65 μg/g,19.33 μg/g, 23.80 μg/g,12.11 μg/g and 0.037 μg/g,their relative standard deviation was between 0.75% and 2.17% and their recovery was between 97.10% and 103.28%. The determination methods have the advantages of rapidity, feasibility and accuracy.
