[Objective] The aim was to determine the trace elements iron, manganese and copper in two kinds of onions. [Method] The trace elements iron, manganese and copper in two kinds of onions were analyzed, with nitric and perchloric acid (4+1) decomposition of the sample, flame atomic absorption spectrometry. [Result] The contents of three kinds of trace elements in onion had significant differences. Among which, the sort of element contents in purple onion was Fe>Mn>Cu, and the sort of element contents in yellow onion was Fe>Cu>Mn. the Fe content in purple onion was more than in yellow onion, and Mn, Cu contents in purple onion were less than in yellow onion. The recoveries were between 94.8%~110.0%, RSD<1.7%. [Conclusion] The contents differences of three kinds of trace elements in purple onion and yellow onion provided data references for dietotherapy of trace elements deficiency patients.
