Zusammenfassung

Nach dem Erhitzen vonN α-Acetyllysin und Glucose für 4 h bei 90 °C in trockenem Zustand und nachfolgender Hydrolyse mit 7.8 N HCl erfolgte eine präparative Fraktionierung der Dihydrochloride von Furosin und Pyridosin durch Kationenaustauschchromatographie. Die Lysinderivate wurden in guter Ausbeute und in für Referenzmaterial ausreichender Reinheit erhalten.

Abstract

After heatingN α-acetyllysine and glucose for 4 h at 90 °C in the dry state and subsequent acid hydrolysis with 7.8 N HCl, preparative fractionation of the dihydrochlorides of furosine and pyridosine was achieved by cation-exchange chromatography. The lysine derivatives could be prepared with high yield and sufficient purity for the use as reference material.
