Compositions of free-sugars and sugar-alcohols in three cultivated mushrooms, Pleurotus ostreatus, Lentinus edodes and Agaricus bisporus were analyzed by gas-liquid chromatography and compositional differences of these components depending on species, sizes of fruiting body and portions(pileus and stipe) were investigated. Glucose, fructose, trehalose, glycerol, arabitol and mannitol were identified in each of the three mushrooms. The major components were mannitol and arabitol in Lentinus edodes, mannitol in Agaricus bisporus, trehalose and mannitol in Pleurotus ostreatus. The total free-sugars and sugar-alcohols content were in the range of 12.7-18.9% in Lentinus edodes, 9.2-16.1% Agaricus bisporus and 8.2-106% in Pleurotus ostreatus. Total contents of these components in Pleurotus ostreatus and Agaricus bisporus were higher in pileus than those in stipe and it was decreased as pileus size development in all three edible mushrooms
