Abstract

A new procedure for determination of biogenic amines (BA): histamine, phenethylamine, tyramine and tryptamine, based on the derivatization reaction with 2-chloro-1,3-dinitro-5-(trifluoromethyl)-benzene (CNBF), is proposed. The amines derivatives with CNBF were isolated and characterized by X-ray crystallography and (1)H, (13)C, (19)F NMR spectroscopy in solution. The novelty of the procedure is based on the pure and well-characterized products of the amines derivatization reaction. The method was applied for the simultaneous analysis of the above mentioned biogenic amines in wine samples by the reversed phase-high performance liquid chromatography. The procedure revealed correlation coefficients (R(2)) between 0.9997 and 0.9999, and linear range: 0.10-9.00 mg L(-1) (histamine); 0.10-9.36 mg L(-1) (tyramine); 0.09-8.64 mg L(-1) (tryptamine) and 0.10-8.64 mg L(-1) (phenethylamine), whereas accuracy was 97%-102% (recovery test). Detection limit of biogenic amines in wine samples was 0.02-0.03 mg L(-1), whereas quantification limit ranged 0.05-0.10 mg L(-1). The variation coefficients for the analyzed amines ranged between 0.49% and 3.92%. Obtained BA derivatives enhanced separation the analytes on chromatograms due to the inhibition of hydrolysis reaction and the reduction of by-products formation.Copyright © 2014 Elsevier B.V.
