|dc.description.abstract||Fractions from methanol extracts of four grades of pine mushroom (Tricholoma matsutake Sing.) were evaluated for their free radical-scavenging and inhibition of nitric oxide production, and the underlying mechanisms were elucidated. The fractions from first-grade pine mushroom exhibited the highest degree of free radical-scavenging and inhibition of nitric oxide production among the various grades of mushroom tested, and free radical-scavenging and inhibition of nitric oxide production by the second-, third-, and fourth-grade mushroom fractions were successively lower. The degree of free radical-scavenging by each fraction decreased in the order ethyl acetate > butanol > diethyl ether > water. Inhibition of nitric oxide production by each fraction decreased in the order ethyl acetate > butanol > water. The ethyl acetate and butanol fractions of methanol-extracted pine mushroom samples exhibited potential anti-oxidative and anti-inflammatory effects that might be attributable to phenolics or flavonoids. © 2006 Elsevier Ltd.
