摘要： 采用火焰原子吸收法同时测定了巨大口蘑中K, Ca, Na, Mg, Fe, Zn, Mn和Cu 8种微量元素的含量。方法的相对标准偏差介于0.1%～2.2%，回收率介于98.1%～106.4%。结果表明，巨大口蘑中Zn, K, Ca, Mg和Mn 等人体必须的生命元素含量较高，揭示了巨大口蘑具有较高的营养价值。

Abstract：The eight trace elements in Tricholoma giganteum Massee, including K, Ca, Na, Mg, Fe, Zn, Mn and Cu, were determined simultaneously by flame atomic absorption spectrometry. The relative standard deviation of the method is 0.1%-2.2%, and the recovery is 98.1%-106.4%. The analytical results were satisfactory. The results showed that some elements essential to human such as Zn, K, Ca, Mg and Mn in Tricholoma giganteum Massee are abundant, implying that the nutritive value of Tricholoma giganteum Massee is high.
