Reinvestigation of the pigments of Pycnoporus sanguineus (Polyporaceae) yielded 4 new pigments of the 2‐amino‐phenoxazin‐3‐one type and the new phenoxazine ether pycnosanguin ( 9 ) besides cinnabarine ( 1 ). Unsubstituted phenoxazin‐3‐one was also shown among the pigments. Isolation and structure elucidation was performed after methylation of the crude acetone extract. The structures were established by spectral analysis and chemical degradations or interconversions.
