Abstract

Topic Description: The citrus fruit consumption and processing industry consumed gigantic masses of by-products such as peels. These are a natural source of bioactive compounds. Few studies have been carried out so far on orange tree by-products, in particular on the peel of some blond and pigmented varieties. The targeted themes particularly concern the analysis of the chemical composition, the identification of the lipid fraction and the study of the antimicrobial and antioxidant activities of certain varieties of oranges (Navels and bitter). Objective: The objective of this study is to determine and compare the antioxidant activity of the peels of seven varieties of oranges cultivated in Algeria and to characterize the phenolic composition by HPLC-DAD analysis. Method: Profiles of free phenolic acids and flavonoids were analyzed by HPLC-DAD, while antioxidant capacities were assessed in vitro using scavenging assay of hydrogen peroxide (HPS), phosphomolybdate method (PMM) and ferrous ion chelating ability (FIC). Results: Among the cultivars tested, Bigarade and Double fine had the strongest antioxidant capacities. Two phenolic acids and seven flavonoids were identified and quantified. Kaempferol was the major flavonoids of C. sinensis L. However, hesperidin, poncirin, apigenin-7-glycoside, naringin, narirutin, and rutin made up the majority of the total flavonoids in the peels of C. aurantium L. Conclusion: orange peels are a natural and renewable source of antioxidants
