Abstract :
HPLC/DAD/ESI/MS analyses were performed to determine the phenolic composition of leaf blade and petiole of the grapevine cv. ‘Cardinal’. The following compounds were identified: the hydroxycinnamic acid derivatives – caftaric acid and coutaric acid, a derivative of sinapic acid and glucose and a derivative of p-coumaric acid and hexose; flavonols – quercetin-3-rutinoside, quercetin-3-galactoside, quercetin-3-glucoside, quercetin-3-glucuronide, kaempferol-3-rutinoside, kaempferol-3-galactoside, kaempferol-3-glucoside and kaempferol-3-arabinoside; and flavan-3-ols – catechin, epicatechin, and procyanidin dimers, as well as procyanidin B1 and B2. The leaf blade was more abundant in phenolic compounds than the petiole. The leaf blade and the petiole had the highest concentration of quercetin-3-glucuronide.
