A rapid ultra-performance liquid chromatographic (UPLC) method for the determination of biogenic amines (putrescine, cadaverine, spermidine, spermine, phenylethylamine, histamine, tyramine and tryptamine) in selected food samples is described. The eight biogenic amines, which are the most important to be determined in food samples, were derivatized with dansyl chloride prior to UPLC separation. The dansylated amines were separated on an Agilent Zorbax Eclipse XDB - C18 column (50 x 4.6 mm ID, 1.8 mu m) using gradient elution with a binary system of acetonitrile-water, a flow rate of 1.0 ml/min and UV detection at 225 nm. The analysis is very fast, all amines are well resolved and are eluted from the column in less than 6 min. The average repeatability of the method ranged between 1.02% and 2.14%. Limits of detection (LODs) for considered amines ranged between 0.032 and 0.098 mu g/l; calibration curves showed very good linearity (r = 0.9994-1.0000). The method was applied to the analysis of amines in pork, beef, chicken and fish meat, cheese and edible Mushrooms. (C) 2009 Elsevier Ltd. All rights reserved.
