Zusammenfassung

Ein Verfahren wird beschrieben zur HPLC-Bestimmung von N-Acetyl-l-glutamin (AC-GLN) in Rattenurin nach Derivatisierung mit Xanthydrol. Die Urinproben wurden von zwei Gruppen von Ratten gesammelt, einer Gruppe mit normaler Ernährung und einer Gruppe mit AC-GLN-Behandlung. Im Urin der unbehandelten Tiere wurden 5 mM/l AC-GLN nachgewiesen; die Ausscheidung bei der anderen Gruppe lag im Bereich von 50 mM/l, entsprechend etwa 50 Gew.% des eingesetzten AC-GLN.

Summary

The determination of N-acetyl-l-glutamine (AC-GLN) in urine of rats after derivatization with xanthydrol by HPLC is described. The urine samples were collected from two groups of rats, one group fed normal nutrition, the other treated with AC-GLN. About 5 mM/l AC-GLN was detected in urine of untreated animals, whereas the excretion of the other group was in the range of 50 mM/l corresponding to about 50 wt.-% of the given AC-GLN.
