[目的]研究柠檬草中Zn、Fe、Cu 3种微量元素的含量。[方法]采用硝酸和高氯酸（体积比为4∶1）分解样品，火焰原子吸收光谱法测定柠檬草中的微量元素Zn、Fe、Cu的含量，对各元素进行加标回收试验，回收率为95.6%~98.8%。[结果]柠檬草中含有丰富的Fe和Zn元素。[结论] Fe元素最多，Cu元素含量最少，为柠檬草的应用提供实践基础。
[目的]研究檸檬草中Zn、Fe、Cu 3種微量元素的含量。[方法]採用硝痠和高氯痠（體積比為4∶1）分解樣品，火燄原子吸收光譜法測定檸檬草中的微量元素Zn、Fe、Cu的含量，對各元素進行加標迴收試驗，迴收率為95.6%~98.8%。[結果]檸檬草中含有豐富的Fe和Zn元素。[結論] Fe元素最多，Cu元素含量最少，為檸檬草的應用提供實踐基礎。

Objective] The aim was to study the elements of Zn, Fe, Cu distribution in Lemon grass. [Method] Nitric acid and per chloric mixed acid were used to digest the sample. Flame atomic absorption spectrometry method for the determination of elements Zn, Fe, Cu contents were used in Lemon grass. Each elements were spiked in recovery test and recovery volume was between in 95.6%~98.8%. [Result] The trace elements of Fe and Zn in Lemon grass were rich. [Conclusion] The Fe was high and Cu was little. These results provided practical foundation for the application of Lemon grass.
