Antioxidant Properties of Extracts from Chroogomphis Rutillus

摘要：

Chroogomphis rutillus is an ectomycorrhizal edible mushroom available in China. The ethanolic, cold water and hot water extracts were prepared and their antioxidant properties studied. At 4 mg/mL, the ethanolic extract showed a high reducing power of 1.561, whereas those of cold water and hot water extracts were 1.161 and 0.808. With regard to the scavenging ability on l,l-diphenyl-2-picrylhydrazyl radicals, extracts were effective in the order: ethanolic>cold water>hot water extracts. EC50 values for chelating ability on ferrous ions for ethanolic, cold water and hot water extracts were 15.755,0.059, and 0.067 mg/mL, respectively. Based on EC50 values, the various extracts from C. rutillus were effective antioxidants.
