Composition of organic acids and fatty acids in three edible mushrooms, Pleurotus ostreatus, Lentinus edodes and Agaricus bisporus were analyzed by gas-liquid chromatography and compositional differences of these components depending on species, sizes and portions (pileus and stipe) were investigated. Lactic, oxalic. fumaric. citric and pyroglutamic acid were identified in each of the three mushrooms and the major organic acids were malic, citric and pyroglutamic acid, respectively. The total organic acid contents were in the range of 2.4-4.0% in Pleurotus ostreatus, 1.7-3.6% in Lentinus edodes and 1.9-3.1% in Agaricus bisporus. Especially oxalic and pyroglutamic acid in Pleurotus ostreatus, malic and citric acid in Lentinus edodes and fumaric acid in Agaricus bisporus were higher in pileus than stipe. The total organic acid contents decreased as the size of pileus developed and especially the decrease of citric acid were marked. On the other hand, the major fatty acids in three mushrooms were linoleic, palmitic and oleic acid. But fatty arid compositions were not significantly different depending on species, sizes and portions.
