Flavonoids are compounds characterized by antioxidant activity, and their intake in the human diet is considered useful for health and nutrition. Non‐anthocyanic flavonoids in 4 different types of Tunisian figs belonging to the smyrna‐type Ficus carica varieties known as Kholi, Tchich Asal, Himri, and Bidhi were studied by liquid chromatography/high‐resolution mass spectrometry UHPLC‐QqTOF. Twenty‐two compounds belonging to the classes of flavanones (naringenin and eriodictyol), flavones (3 apigenin and 5 luteolin derivatives), and flavonols (2 kaempferol and 7 quercetin derivatives) were identified. Three O ‐methoxy flavonols (tamarixetin, syringetin, and isorhamnetin‐3‐ O ‐glucoside) were found in figs for the first time. Total content of non‐anthocyanic flavonoids found in dark varieties (between 410 and 830 mg/kg) show that these F . carica are fruits qualitatively and quantitatively rich of dietary polyphenols .
