摘　　要：目的：测定佛手中锌（Zn）、铜（Cu）、锰（Mn）、铁（Fe）4种微量元素的含量。方法：采用微波消解法处理佛手，利用火焰原子吸收法对佛手中Zn、Cu、Mn、Fe 4种微量元素含量进行测定分析。结果：佛手中Zn、Cu、Mn、Fe含量分别为23.33、4.51、12.13、138.54μg/g。结论：火焰原子吸收光谱法简单、准确，方法加标回收率在98.9%～101.3%，相对标准偏差（RSD）在0.38%～1.06%之间。Objective：To determine the contents of Zn, Cu, Mn and Fe contained in bergamot. Methods：Berg-amot was dealt by microwave digestion method, the contents of Zn, Cu, Mn and Fe contained in bergamot were de-termined and analyzed by flame atomic absorption method（FAAS）. Results：The contents of Zn, Cu, Mn and Fe con-tained in bergamot were 23.33, 4.51, 12.13 and 138.54μg/g respectively. Conclusion：The method is simple and ac-curate, the recovery rate of the method is over the range of 98.9%to 101.3%, and RSD over the range of 0.38%to 1.06%.
