Methanol and hot water extracts of Suillus granulatus were investigated for its antioxidant activity, polyphenol content and tyrosinase inhibitory effect. The antioxidant activity was evaluated using 1, 1- dipheny l-2-picrylhydrazyl (DPPH) scavenging assay. The antioxidant activities of hot water and 80% methanol extracts of Suillus granulatus fruiting body were 51.49%. and 90.58% at 1.5mg/ml concentration. Total polyphenol content of hot water and 80% methanol extracts were 33.21㎍ GAEs/mg and 27.97㎍ GAEs/mg. Tyrosinase inhibitory activity of water extract was 7.8% while 80% methanol extract was 20.88% at 1mg/ml concentration.
