In these last two decades, epidemiological studies have provided evidence of beneficial health effects of dietary fruits and vegetables; at least part of such effects have been attributed to secondary metabolites commonly referred to as phenolics. These compounds are widely distributed in the plant kingdom, but levels and chemical forms vary markedly depending on the plant source and their biological value make the phenolic compounds found in plants interesting to identify and characterize. HPLC-DAD-ESI-MSn is the method of choice for such investigations. Furthermore, data-dependent acquisition, where user-specified criteria are applied to select the ion of interest for subsequent fragmentation, are among the most common approaches employed to identify unknown compounds by MS.

Abstract
In these last two decades, epidemiological studies have provided evidence of beneficial health effects of dietary fruits and vegetables; at least part of such effects have been attributed to secondary metabolites commonly referred to as phenolics. These compounds are widely distributed in the plant kingdom, but levels and chemical forms vary markedly depending on the plant source and their biological value make the phenolic compounds found in plants interesting to identify and characterize. HPLC-DAD-ESI-MSn is the method of choice for such investigations. Furthermore, data-dependent acquisition, where user-specified criteria are applied to select the ion of interest for subsequent fragmentation, are among the most common approaches employed to identify unknown compounds by MS. This work is focused on the fingerprint of the polyphenolic fraction of “Variegato di Castelfranco” saladI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
