Date palm (Phoenix dactylifera L.), a strategic oasian species in most Mediterranean regions, is often known by the commercialized Deglet Nour variety. However, many other common varieties that might have high importance are neglected. The current study aims to evaluate the nutraceutical and functional properties of six common date palm cultivars, collected from three Tunisian oasian regions. The biochemical composition and antioxidant potential of these date cultivars were investigated.

Abstract In this study, the antioxidant activities and detailed phenolic profiling of extracts from seven cultivars of date seeds were investigated. Significant differences were detected among cultivars. Total phenolic content (TP) ranged between 135.9±12.1 and 284.86±21.9 mg GAE/g DM. The total flavonoid value varied between 34.20±0.34 and 94.46±1.04 mg RE/g DM. The condensed tannin ranged from 24.17±1.13 to 201.60±9.95 mg CTE/g DM. Phloroglucinolysis was used to depolymerize the bound polyphenols.
