    Evaluation Of Antioxidant Activity And Polyphenolic Contents Of Two South Algerian Eggplants Cultivars
    (University of Eloued جامعة الوادي, 2016-05-01) Djouadi, A.; Lanez, T.; Boubekri, C.
    Polyphenolic compounds and antioxidant activity in eggplants (Solanum melongena L.) seem to depend on cultivar, maturity stage, environmental conditions and the part of the fruit. In this work, the polyphenolic content and antioxidant activity of pulp, whole fruit and peel from fresh dark-purple and white eggplant varieties cultivated in Southern Algeria were measured. Total phenolic content were determined by Folin-Ciocalteu test, and antioxidant activity measured using cyclic voltammetry. Correlations between antioxidant activity and total phenolic content were also examined. Within each cultivar, the total phenolic content and antioxidant activity were highest in the peels, followed by the whole fruit and the pulp. In the peel, whole fruit and pulp the dark-purple eggplant had the highest total phenolic contents and the highest total antioxidant activities.

    Study Of Antioxidant Capacity Of Different Parts Of Two South Algerian Eggplant Cultivars
    (University of Eloued جامعة الوادي, 2012-07-01) Boubekri, C.; Rebiai, A.; Lanez, T.
    In this study the antioxidant capacity of ethanolic EE and water WE extracts fromdifferent parts (calyx, peel, and pulp) of eggplant (Solanum melongena L) were evaluated using cyclic voltammetry.The antioxidant capacity of different parts of eggplant was measured using ascorbic acid equivalent antioxidant capacity assays. The peel extracts of both dark purple and white samples showed the highest antioxidant capacity (66.78and 75.62 mg/g) followed by pulp (16.54 and 30.56 mg/g), and calyx (14.82 and 21.27 mg/g). These results indicate that antioxidant capacity of eggplant varied by parts and solvents.
