Abstract

A red pigment associated with pink stain of angiosperm and gymnosperm woods caused by the fungus Arthrographis cuboidea was isolated, purified to crystalline form, spectroscopically characterized and identified as 5,8-dihydroxy-2,7-dimethoxy-l,4-naphthalenedione. Results also suggest that other naphthoquinone pigments may be associated with the pink stain. This is the first report on the chemical nature of the red pigment responsible for pink stain in wood.
