in maximaler Ausbeute zu gewinnen. Die Isolierung erfolgte mittels einer Festphasenextraktion auf einer Si-2OH Säule. Die densitrometrische Bestimmung wurde mittels HPTLC auf Kieselgel-beschichteten Platten durchgeführt. Die Ergebnisse zeigten, daß der reine Farbstoff in einer Konzentration von 4,85%. im Kernholz vorliegt.
