Gloeostereum incarnatum is an edible and medicinal mushroom belongs to Family Cyphellaceae of Polyporales, Basidiomycota. The purpose of this study was to investigate the free radical scavenging, anti- inflammatory, and melanin synthesis inhibitory activities of fruiting bodies of Gloeostereum incarnatum. In the free radical scavenging activities, the mushroom extracts showed good 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and chelating activity on the ferrous ions compared with the positive control, BHT. The mushroom extract suppressed nitric oxide (NO) production in LPS- induced RAW 264.7 macrophage cells in dose dependant manners. Significant reduction of paw edema of rats were observed at 2~6 h after administration with 50 mg/kg of the methanol and hot-water extracts, which were comparable with treatment of 5 mg/kg of indomethacin, the positive control. The melanin synthesis of Melanoma B16/F10 cells treated with 100 μg/mL of the methanol and hot water extracts decreased melanin concentration to 50% and 45% compared with the control, arbutin. Therefore, the experimental results showed that methanol and hot-water extracts of Gloeostereum incarnatum fruiting bodies might be used for good sources of anti-inflammatory, free radical scavenging, and skin whitening agents for human health.
