investigation of the flavonoids regarded the identification and quantification of seven components (quercetin, rutin, kaempferol, kaempferol-3-glucoside, kaempferol-3-rutinoside, rhamnetin, isorhamnetin) through a fast method that involves the use of wine as it is, as suggested by Viñas et al. (14). The wine samples from Campania are characterized by a higher content of flavonoids and flavonoid-glucosides and show a composition, both qualitatively and quantitatively, similar. Of the seven compounds analysed in the flavonoids group, quercetin (
