目的：对云南普洱茶、贵州苦丁茶、河北茉莉花茶中的锌(Zn)、铁(Fe)、铜(Cu)、锰(Mn)4种微量元素进行测定。方法：将样品用干法进行消解，并利用火焰原子吸收光谱法测定3种茶叶中Zn、Fe、Cu、Mn 4种微量元素的含量。结果：Zn、Fe、Cu、Mn 4种微量元素在3个地区茶叶中含量分别是云南普洱茶：43.43μg/g、57.28μg/g、33.14μg/g、135.67μg/g；贵州苦丁茶：19.91μg/g、32.98μg/g、9.74μg/g、77.08μg/g；河北茉莉花茶：36.09μg/g、84.37μg/g、28.52μg/g、220.08μg/g。结论：3种茶叶中均含有丰富的微量元素，不同地区茶叶中微量元素含量有一定差异。

Objective: To determinate the content of the trace elements(Fe, Mn, Zn, Cu)in Yunnan Pu'er tea, Hebei jasmine tea, Guizhou Kuding tea. Methods:Nitric acid and perchloric acid(4+1)were used to disintegrate the ground sample of tea. Flame atom-ic absorption spectrometric method was used to determine four trace elements content in three kinds of tea. Results: The content of trace elements(Zn, Fe, Cu, Mn)in three districts is respectively that Yunnan Pu'er tea:43.43μg/g , 57.28μg/g , 33.14μg/g , 135.67μg/g , Guizhou kuding tea: 19.91μg/g , 32.98μg/g , 9.74μg/g , 77.08μg/g , Hebei Jasmine tea: 36.09μg/g , 84.37μg/g , 28.52μg/g , 220.08μg/g . Conclusion:All three kinds of tea contain rich trace elements and there are differences about the content of trace ele-ments in different areas.
