    Description / Table of Contents: Fungus Pigments, 4141).  -  Naphthoquinone Pigments from the Slime Moulds Trichia floriformis and Metatrichia vesparium (Myxomycetes)Trichione (1) is the red main pigment of fruiting bodies from the slime mould Trichia floriformis. It contains a 2,5-dihydroxynaphthoquinone chromophore, substituted in position 3 by an unsaturated side chain carrying a terminal hemimalonate moiety. Homotrichione (7) differs by the presence of two additional CH2 groups in the side chain. It co-occurs with arcyriaflavin B (5), arcyriaflavin C (6) and further pigments in Metatrichia vesparium.
    Notes: Die Fruchtkörper des Schleimpilzes Trichia floriformis enthalten als roten Hauptfarbstoff Trichion (1), ein 2,5-Dihydroxynaphthochinon, das in 3-Stellung eine ungesättigte Seitenkette mit terminaler Malonhalbester-Gruppierung trägt. Homotrichion (7) unterscheidet sich nur durch eine um zwei CH2-Gruppen längere Seitenkette. Es kommt neben 1, Arcyriaflavin B und C (5 bzw. 6) und weiteren Farbstoffen in Metatrichia vesparium vor.
