ABSTRACT

The leave and peels of pomegranate plants were manually separated and mechanically pressed to obtain their crude juices. The phytochemical results indicated that pomegranate peel juice contained high quantities of polyphenols and flavonoids, being about 1.22 and 1.43 times as great as that of leave juice, respectively. Crude peel juice possessed powerful antioxidant activity than leave crude juice, being approximately 6.59 times as great as that induced by leave juice. HPLC was used to characterize the polyphenolic compounds in pomegranate leave and peel juices. Thirty and eight polyphenolic compounds were separated from pomegranate peel and leave, respectively and nearly 50% of these compounds were quantitatively determined. The basic compounds found in pomegranate peel and leave juices were gallic acid, protocatechuic acid and gallic acid, 3-hydroxy tyrosol, respectively.

Keywords: Pomegranate peels and leave juices, phytochemical screening analyses, polyphenols, flavonoids, HPLC analyzer.
