초록

Methanol and hot water extracts of Daedalea bien-nis were investigated for its antioxidant activity, poly- phenol content and tyrosinase inhibitory effect. The antioxidant activity was evaluated using 1, 1-diphenyl -2-picrylhydrazyl (DPPH) scavenging assay. The antioxidant activities of hot water and 80% methanol extracts of Daedalea biennis fruiting body were 52.06%. and 92.62% at 1.5mg/ml concentration. Total polyphenol content of hot water and 80% methanol extracts were 12.26㎍ GAEs/mg and 13.69㎍ GAEs/mg. Tyrosinase inhibitory activity of water extract was 19.70% while 80% methanol extract was 15.75% at 1mg/ml concentration.
