The fruiting bodies of the carrot truffle Stephanospora caroticolor were extracted yielding two pigments, 2-chloro-4-nitrophenol and stephanosporin. The structure of stephanosporin was confirmed by synthesis followed by analysis by GC/MS. Also isolated were 4-hydroxyacetanilide, 4-amino-2-chlorophenol and 4-nitrophenol. A scheme for the enzymic degradation of stephanosporin to 2-chloro-4-nitrophenol is presented.
