Abstract

Variability of trans- and cis-resveratrol and their glucosides in red wines produced in Sardinia and Corsica was determined by HPLC. The data obtained were elaborated by multivariate statistical analysis (Principal Component Analysis). The results showed a higher average total stilbene content in Corsican samples than in Sardinian samples, due to the aglycons content. Furthermore, PCA pointed out a good separation between the two groups which seems to be related to the samples origin. Lastly, the Cagnulari, which is a particular Sardinian cultivar, showed high values of total stilbenes, related to the glucoside content, as did three Corsican samples.
