Abstract
Nine pomegranate cultivars grown in Spain were selected, and their physicochemical (total soluble solids, pH, titratable acidity, maturity index, monomeric anthocyanin pigment, flavonoids, hydrolyzable tannins, and vitamin C) and antioxidant properties and polyphenolic composition of the juices were compared. A total of 53 polyphenols were identified, showing cultivars different profiles. Of all nine cultivars, Katirbasi had the highest contents of flavonoids, hydrolyzable tannins and vitamin C, as well as gallic acid and ellagic acid contents, explaining its high total reducing capacity. Principal component analysis allowed Katirbasi to be differentiated clearl...
