Amino and Fatty Acids of Wild Edible Mushrooms of the Genus Boletus

 A comparative study on the free amino acids of 15 wild edible mushroom species belonging to the genus Boletus (phylum Basidiomycota) was developed. The major amino acids in the fruit bodies were arginine , alanine, glutamine, and glutamic acid. The most abundant fatty acids were oleic ( 9-18:1), linoleic acid (9,12-18:2) , and palmitic acid (16:0), but a great variation of the ester composition from one to another one was found. Chemical constituents were characterized by GC-MS, and other chemical methods.
