Single-step high-performance liquid chromatographic method for the analysis of acetylated polyamines.

A high-performance liquid chromatography method for the determination of urinary acetyl derivatives of the polyamines putrescine, cadaverine and spermidine is described. This procedure utilizes an ion-exchange column for the separation of acetyl derivatives and the compounds are quantitated by fluorescence after reaction with o-phthalaldehyde. The steps necessary for sample preparation are minimized, and the assay is both sensitive and reproducible. This chromatographic procedure was used for the determination of the urinary acetylated polyamines of seven normal volunteers and three cancer patients.
