Free-Radical Scavenging Activity of Submerged Mycelium Extracts from Higher Basidiomycetes Mushrooms

Twenty-four Basidiomycetes strains were evaluated to determine their free-radical scavenging capacity in submerged cultivation. The scavenging capacity of the extracts varied from 1 to 85% depending on the mushroom species, solvent used, and concentration. A calculation of EC₅₀ of extracts from several wood-rotting Basidiomycetes showed high scavenging abilities at low effective concentration.
