Seventy-three Southern Italian red wines were characterized according to their content in total polyphenols, trans and cis-resveratrol and biogenic amines. These quality parameters were used in multivariate statistical analysis to discriminate the wines according to their specific geographical origin. The results indicated that total polyphenols, resveratrol isomers, and biogenic amines provide a good prospect for discriminating wines by regions. The discrimination was also possible to a lesser extent by cultivar. In particular, Canonical Variate Analysis suggested that the discrimination of wines according to their provenance is based on the following parameters: cis-resveratrol, total polyphenols, spermidine and tryptamine for Basilicata region; agmatine and trans-resveratrol for Calabria and Campania regions; cadaverine, ethanolamine, histamine, putrescine and tyramine for Puglia region.

Abstract

Seventy-three Southern Italian red wines were characterized according to their content in total polyphenols, trans and cis-resveratrol and biogenic amines. These quality parameters were used in multivariate statistical analysis to discriminate the wines according to their specific geographical origin. The results indicated that total polyphenols, resveratrol isomers, and biogenic amines provide a good prospect for discriminating wines by regions. The discrimination was also possible to a lesser extent by cultivar. In particular, Canonical Variate Analysis suggested that the discrimination of wines according to their provenance is based on the following parameters: cis-resveratrol, total polyphenols, spermidine and tryptamine for Basilicata region; agmatine and trans-resveratrol for Calabria and Campania regions; cadaverine, ethanolamine, histamine, putrescine and tyramine for Puglia region.
