Abstract

Abstract: 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)μg/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.

Key words: Termitomyces, amino acid, selenium
