(A) Total phenolic content in peels, seeds, and leaves of pomegranate fruit growing in different regions of the world [49,50,52,54,55,56]. BR: Berkane region; SR: Statte region; BMR: Beni Mellal region; UC: unknown cultivar; MWE: methanol/water extract; n-BF1: n-butanol fraction of hydromethanolic extract; CE2: aqueous-acetone crude extract; EAF2: ethyl acetate fraction of aqueous-acetone extract; n-BF2: n-butanol fraction of aqueous-acetone extract; Chelfi-ES: chelfi exposed to sun; Chelfi IC: Chelfi in shade. (B) Total flavonoid content in pomegranate leaves, peels, seeds, and flowers, from different geographical areas of the world [49,52,53,54,56]. BMR: Beni-mellal region; SR: Statte region; BR: Berkane region; UC: unknown cultivar. As shown, the Iranian and Algerian varieties seem to accumulate very important quantities of these bioactive constituents. Furthermore, the final results are sensitive to different factors such as the solvent used for the extraction, genetic variabilities, variety, and the geoedaphic and climatic conditions that characterize each country.
