摘　　要：采集获得四川省内10种鸡枞菌,利用全自动氨基酸分析仪测定其氨基酸组成及含量,利用原子荧光光度仪分析其硒元素含量,并利用统计学方法进行分析。结果表明:鸡枞菌子实体氨基酸含量高,总氨基酸为15.92%～28.86%,必需氨基酸含量分别为7.08%～10.20%,普通鸡枞、裂纹鸡枞、乌黑鸡枞、谷堆鸡枞、粗柄鸡枞及小鸡枞的氨基酸含量均超过20%,其中谷堆鸡枞总氨基酸及必需氨基酸分别达到28.86%、10.20%。鸡枞菌中硒含量亦较高,为长根菇的3～18倍,其中乌黑鸡枞含量达到(1.2286±0.0340)μg/g。可见四川省鸡枞菌氨基酸种类、硒含量丰富,营养价值高。Fruiting body samples of 10 species of Termitomyces grown in different regions of Sichuan province were analyzed for their amino acid composition using amino acid auto analyzer and Se content using atomic fluorescence spectrometer. The results showed that the contents of total amino acids and essential amino acids were 15.92% - 28.86% and 7.08% - 10.20%, respectively in the fruiting bodies of the investigated species of the genus Termitomyces. The fruiting bodies of T.albuminosus, T. robustus, T. badius, T. microcarpus, T. schimperi and T. heimi exhibited a total amino acid content of more than 20% and the contents of total amino acids and essential amino acids in T. heimii fruiting bodies were 28.86% and 10.20%, respectively. Besides, Se content of Termitomyces fruiting bodies was 3- 18 times higher than that of Xerula radicata, and the Se content of T. badius was （1.2286 ± 0.0340） μ g/g. It could be concluded that the 10 investigated species of Termitomyces grown in Sichuan province are rich in a variety of amino acids and Se and are highly nutritious.
