Abstract

An analytical method for determination of the biogenic amines tryptamine, putrescine, histamine, phenylethylamine, tyramine, cadaverine, spermidine and spermine in red and white wines using pre- column derivatization with dansyl chloride (DnsCl) and reversed phase-high performance liquid chroma- tography with diode array detector (RP-HPLC-DAD) was developed and optimized. The concentration of DnsCl, pH, time of reaction and evaporation under nitrogen were tested and optimized. Best recoveries, ranging from 72 to 102 % were obtained for all analyzed amines applying derivatization with 10 mg/ml of DnsCl for 1 h at 60 oC and pH 9. The developed method showed excellent linearity with R2 > 0.99 for all of the tested amines. The accuracy was checked with the standard addition method showing satisfactory recovery, good repeatability and reproducibility. The optimized and validated method was applied for the analysis of white and red wines from Macedonian origin, observing higher total amounts of biogenic amines in red wines. The content of the individual biogenic amines was below the maximal allowed concentration in all tested wines.
