In the present paper, the contents of Ca, Fe, Zn, Mg, Cu, Mn, Cr, Pb and Cd in garlic which comes from different groups of Xinjiang were measured by wet digestion and flame-atomic absorption spectrometry. And the standard addition recovery experiment was done. The results of recovery experiment show that the atomic absorption spectrometry is a quick and easy method for determining; The correlation coefficient of each standard curve was between 0.994 4 and 0.999 8, with good linear relationship; The relative standard deviation (RSD) of each result is less than 5.15%, the recovery rate of each sample was between 99.4% and 101.7%, and the determination results are correct and reliable. The results show that the beneficial elements are richer in the garlic of Xinjiang, and the contents of trace elements are different among different places. To some extent, the difference in contents reflects the difference in the topography, climate, soil, hydrology and other environmental factor between the south and the north of Xinjiang.
