Abstract
The biologically active amines agmatine, cadaverine, histamine, phenethylamine, putrescine, spermidine, and tyramine have been determined in different varieties of grape, aszu grape, wine and aszu wine from the Tokaj region of Hungary. Ion pairs formed between the amines and octanesulphonic acid were separated by liquid chromatography on a μBondapak C18 reversed-phase column, and spectrofluorimetric detection was performed after post-column derivatization witho-phthalaldehyde and 2-mercaptoethanol. The method was linear for the amines between 0.1 and 10 mg L−1, and for spermidine between 1 and 30 mg L−1.
