This study examined the variability of compounds with antioxidant activity in wines coming from native cultivars of Sardinia. Hydroxycinnamic acids, resveratrols, anthocyanins, flavanols and total polyphenols concentrations were determined in 27 samples of wine from different parts of the island. The data obtained enabled quantification of the concentration of antioxidant molecules present in the different cultivars. Moreover, Principal Component Analysis (PCA) elaboration enabled possible discrimination to be detected between the cultivars examined depending on certain classes of compounds.

Abstract
This study examined the variability of compounds with antioxidant activity in wines coming from native cultivars of Sardinia. Hydroxycinnamic acids, resveratrols, anthocyanins, flavanols and total polyphenols concentrations were determined in 27 samples of wine from different parts of the island. The data obtained enabled quantification of the concentration of antioxidant molecules present in the different cultivars. Moreover, Principal Component Analysis (PCA) elaboration enabled possible discrimination to be detected between the cultivars examined depending on certain classes of compounds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
