Physiological activities of 70% methanol, fermented ethanol and hot-water extracts of Pleurotus eryngii were investigated. Free radical scavenging activities of P. eryngii extracts were determined according to the elimination of DPPH radicals. Their nitrite scavenging activity and total polyphenol content were also determined. Amino acid analysis showed that phenylalanine (Phe) and glutamic acid (Glu) are most abundant essential and non-essential amino acids in the analyzed extracts. The hot-water extract of ASI 2394 represented the highest antioxidant activity with the DPPH radical scavenging rate value of 40.97±1.65%. ASI 2820 displayed the superior capacity to eliminate nitrate regardless of extraction solvents. The hot-water extract of ASI 2887 had the highest content of polyphenol. Our results showed that P. eryngii is well qualified as a functional food.
