Abstract
Variability of trans - and cis -resveratrol and their glucosides in red wines, coming from 13 different species of vine grown on two parallel plots of land, different for pedo-climatic conditions, during three different vintages, was determined by HPLC. The data obtained were elaborated by multivariate statistical analyses (Principal Component Analysis and Discriminant Analysis). The results showed that trans - and cis -resveratrol are more correlated than transand cis -glucoside, due to the uniformity of vinification treatments. Furthermore, Principal Component Analysis pointed out a good separation among five types of wine (Pinot noir, Malbeck, Gaglioppo, Refosco and Ciliegiolo), coming from the same cultivars, which are also discriminated in the Discriminant Analysis as a function of resveratrol content. This would underline that the cultivar variable, almost for the five above mentioned cultivars, has a higher influence than the other factors in wine characterisation with respect to their content of resveratrol.
