Zusammenfassung

Verdünnte Lösungen von KMnO4 erleichtern das Röten von Blüten des Farbensafrans (C. tinctorius). In dem geröteten Gewebe wurden beträchtliche Mengen derCarthamus-Farbe visuell gefunden. Daher wurde diese isoliert und durch aufeinanderfolgende Säulen-Chromatographie mit verschiedenen Lösungsmitteln gereinigt. Weiterhin wurde der rote Farbstoff chromatographisch und spektroskopisch charakterisiert. Die analytischen Daten ergaben die Identität mit Carthamin. Die Nützlichkeit der gegenwärtigen angewandten Technik wurde mit der üblichen routinemäßig angewandten verglichen.

Summary

A diluted solution of KMnO4 was found to facilitate the reddening of the detached florets from dyer's saffron (Carthamus tinctorius) flowers. In the reddened tissues, substantial amounts of aCarthamus dye was detectable visually. This was isolated and purified through successive column chromatography using various solvent systems. A red colouring matter obtained was characterized chromatographically and spectroscopically. The analytical data proved that the pigment is identical with carthamin. This new technique was evaluated by comparing it with the procedures usually applied.
