Xylindein

Xylindein is a quinone pigment, a dimeric naphthoquinone derivative. It is produced by fungi in the genus Chlorociboria. This pigment causes green staining of wood infected by the fungi.

Etymology

This pigment was first extracted in 1868 by Paul Thénard from wood. It resembled indigo, so he called it xylindéine, from the combination of xyl- and indé + -ine.
