The purpose of this study is to investigate the physiological activities of the water and ethanol extracts from three strains of Hypsizygus marmoreus. Anti-oxidant and anti-tumorigenic activities were carried out. As the anti-oxidant test ORAC(Oxygen Radical Absorbance Capacity) assay was performed. Nitrite scavenging activity and MTT assay were conducted to confirm the anti-tumorigenic activities. HeLa and A549, MCF-7 cell lines were used for MTT assay. GONJI No.6 ethanol extract showed highly effects on anti-tumorigenic activities among three strains. But water extracts were not shown anti-tumorigenic activities. As a result of the anti-oxidant activity the Hypsizygus marmoreus(from Japan) water extract showed highest radical absorption activities on ORAC assay.
