This study was conducted to determine the nutritional compositions and antioxidant activities of Pleurotus ostreatus, Pleurotus eryngii, and Agaricus bisporus in Korea. The moisture, protein, ash, and fat contents ranged from 89 to 93%, 2.6 to 2.9%, 0.5 to 0.9%, and 0.1 to 0.3%, respectively. The K content was highest among minerals, while the levels of P, Mg, and Na were relatively higher than other mineral contents. Vitamin contents of the mushrooms were highest in ergosterol, followed by vitamin B3, C, B1, folate, and B12. Except for vitamin B1, Pleurotus eryngii contained higher amounts of vitamins than Pleurotus ostreatus. The levels of ergothioneine and beta-glucan were highest in P. eryngii at 22.4 mg/100 g and 5.0 g/100 g, respectively. The contents of gamma-aminobutyric acid and total polyphenols were highest in Agaricus bisporus at 8.3 mg/100 g and 47.1 mg gallic acid equivalent/100 g, respectively. The 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities of the A. bisporus were relatively higher than others. These results provide basic information about health-beneficial effects of frequently consumed mushrooms in Korea.
