摘要：

Schiff bases of the diamines 1,3-diaminopropane, putrescine, and cadaverine and the polyamines spermidine and spermine with pyridoxal or pyridoxal phosphate occur in human urine, as shown by gas chromatographic/mass spectrometric selected ion-monitoring techniques. By use of synthetic standards, procedures were devised for conversion of the Schiff bases to stable derivatives amenable to gas chromatographic/mass spectrometric analysis. These procedures involve borohydride reduction of the C=N double bond, hydrolytic removal of the phosphate group, chromatographic separation from the bulk of urinary constituents, and trifluoroacetylation of polar functional groups. The levels of the polyamine-pyridoxal Schiff bases were estimated to be in the range of pmol/ml of urine.
