Abstract
“Suspect screening analysis”method to study grape metabolomics, was performed. This method is
a middle-way “targeted” and “untargeted”approach aiming at identifying the largest number of metabolites in
grape samples. A new database of putative grape and wine metabolites (GrapeMetabolomics), which currently
contains around 1,100 compounds, was constructed by CREA at Conegliano. By performing high-resolution
mass spectrometry analysis of the grape extract in both positive and negative ionization mode, averaging 320-
450 putative compounds are identified. Most of them are grape polyphenols, such as anthocyanins, flavonols
and stilbene derivatives. By performing PCA and Cluster Analysis the composition in anthocyanins and
flavonols of 20 Italian red grape varieties, was studied
