Four so far unknown red alkaloid pigments, haematopodin B ( 1 ) and the mycenarubins D ( 3 ), E ( 5 ) and F ( 6 ), were isolated from fruiting bodies of Mycena haematopus . The structures of these pyrroloquinoline alkaloids were established by 2D NMR spectroscopic and MS (ESI) methods. Their absolute configurations were determined by comparison of their CD spectra with that of haematopodin ( 2 ) or mycenarubin A ( 4 ). Metabolic profiling of the red pigments of intact and injured fruiting bodies revealed that the known degradation product haematopodin ( 2 ) originates from haematopodin B ( 1 ), which is the native main pigment of M. haematopus .(© Wiley‐VCH Verlag GmbH & Co.
