The amino acids of Pleurotus nebrodensis and Pleurotus eryngii in Xinjiang were analyzed.The result showed that 17kinds of amino acid content in Pleurotus nebrodensis and Pleurotus eryngii were abundant,and the proportion of EAA in total amino acid were 34.72% and 37.92% respectively.But the total amino acid content of Pleurotus nebrodensis(16.80%)was higher than that the of Pleurotus eryngii(14.34%).This proved that the edible mushrooms could be regarded as the necessary supplement for human being to obtain amino acids.
