Abstract (EN): Ficus carica L., Moraceae, is one of the first plants that were cultivated by humans, being the fruit an important crop worldwide for dry and fresh consumption. In this work, phenolics and antioxidant potential of dried fruits of seventeen Tunisian F. carica varieties, from green, red and black phenotypes, were assessed for the first time. HPLC-DAD analysis was performed. All samples presented a similar qualitative profile. The phenolics content ranged between 29.18 and 55.56 mg/kg (in black and red phenotypes, respectively) and quercetin-3-O-rutinoside was always the major compound. The antioxidant potential against DPPH center dot, superoxide and nitric oxide radicals of three varieties representing each phenotype was checked. All samples exhibited activity against the first two radicals in a concentration-dependent way, "Bayoudi" variety being the most effective one (IC25 values of 10.32 and 2.89 mu g/mL, respectively). Nevertheless, only "Hammouri" variety presented some capacity to scavenge nitric oxide radical. Our results reveal nice perspectives for these typical fruits, as they present an interesting phenolic composition and good antiradical activity and may encourage their consumption for health protection.
