Özet

Arils from six pomegranate (Punica granatum L.) cultivars obtained from various sites from the Mediterranean region of Turkey were evaluated for their chemical and antioxidant properties. These properties included total phenolics (TP), total monomeric anthocyanins (TMA), soluble solids (TSS), titratable acidity (TA), individual sugars and organic acids. Antioxidant capacities of arils were determined by both the ferric reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity (TEAC) assays. The antioxidant capacities averaged 5.60 and 7.35 mmol TE/I by the TEAC and FRAP methods. Variability among cultivars was greatest for TMA content (CV 132%): individuals ranged from 6.1 to 219 mg cy3-Gluc 1(-1). TP means averaged 1507 mg GAE/l Levels of FRAP, TEAC, TP, and TMA were strongly correlated (r = 0.82-0.96). The major sugars were fructose (6.4 g/100 ml) and glucose (6.8 g/100 ml), the major acids were citric (1.78 g/100 ml) and malic (0.12 g/100 ml). (c) 2008 Elsevier Ltd. All rights reserved.
