Abstract：In order to study the nutritional value of different kinds of wild edible mushrooms from different regions of Gui-zhou Province,free amino acids in 24 wild edible mushrooms were detected.The results showed that the contents of total amino acids in 24 kinds of wild edible mushrooms were significantly different,the content of total amino acids was 125.28-356.38 mg·g-1,the essential amino acid were complete the content of essential amino acid was 50.7-144.76 mg·g-1 the content of taste amino acids and medicinal amino acid were rich.Evaluate different types of amino acids through various indicators such as amino acid ratio(RAA)and amino acid ratio coefficient(RC),it is known that most edible wild mush-rooms are rich in amino acids through various amino acid nutritional value evaluation methods,that can be used as a high-qual-ity protein source in human mode.The highest nutritional value of amino acids is M24(68.24),and the lowest is M3(33.48).Principal component analysis and cluster analysis showed that the best overall quality is M6(0.94)and the worst is M9(-1.39).So the amino acid composition of wild edible mushrooms were related to their species and growth regions.
