The indophenol-reducing compound, 4-hydroxy-3,6-dimethyl-2H-pyrane-2-one (I), was isolated from the culture filtrate of an unidentified fungus. I also reacted with the DPPH radical to form a reaction product IV which was determined to be 1-[4-(3,4-dihydro-3,6-dimethyl-2,4-dioxo- 2H-pyran-3-yl)phenyl]-1-phenyl-2-picrylhydrazine. This is the first report describing the formation of an adduct of the DPPH radical and its scavenger.
