Pigments of fungi. Part 40. Dermocanarins 1–3, unique naphthol- and naphthoquinone-anthraquinone dimers that contain a macrocyclic lactone ring from the fungus Dermocybe canaria Horak

Abstract

The dermocanarins 4–6 are unique naphthylanthraquinones containing a nine-membered lactone ring that have been isolated as the principal pigments of the subterranian mycelium of the fungus Dermocybe canaria and their structures determined by spectroscopic methods. In the fruit bodies of this fungus physcion 8-O-β-D-glucopyranoside 12 accompanies the aglycone 1 as the major colouring matters.
