Boletus edulis, edible mushrooms, fatty acids, human nutrition, Poland


The aim of this study was to determine the content of fat and fatty acid profile in wild Boletus edulis. The research material consisted of 33 samples of wild Boletus edulis in the form of cups and stems, collected from four selected regions of Poland. Methyl esters of fatty acids were prepared by Peisker’s method. Separation of the examined compounds was performed by gas chromatography (FID). The dominant fatty acids in all samples under study were: C18:2, C18:1 and C16:0. The profile of fatty acids in Boletus edulis varied between the regions where the mushrooms were collected as well as the morphological parts of the fruiting body.
