Antioxidant Activities of Cold Water Extracts from Hohenbuehelia serotina and Armillaria mellea
Cold water extracts from Hohenbuehelia serotina and Armillaria mellea fruit bodies were prepared and their antioxidant properties were investigated in three different assays, namely, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, reducing power and chelating ability on ferrous ions. Results showed that, at 4 mg/mL, the cold water extracts from A. mellea showed a high reducing power of 1.540. With regard to DPPH free radical scavenging abilities, EC50 value of extracts from A. mellea was 0.595 mg/mL, while that of extracts from H. serotina was 1.649 mg/mL. EC50 values for chelating ability on ferrous ions for cold water extracts from A. mellea and H. serotina was 0.319 and 0.685mg/mL, respectively. From EC50 values obtained, it can be concluded that cold water extracts from H. serotina and A. mellea were good in antioxidant properties.
