Antioxidant Activities, Total Phenolic Content and Colour Parameters in the Aqueous Extracts of Avocado, Banana and Papaya Leaves

Literature has consistently reported that horticultural wastes including leaves, skin, stones and seeds contain substantial amounts of bioactive compounds. Therefore, this study aims to evaluate antioxidant activity, Total Phenolic Content (TPC) colour parameters in avocado, banana, papaya leaves. Antioxidant activity the leaves was determined using Trolox Equivalent Capacity (TEAC) DPPH radical scavenging assays, whereas TPC evaluated Folin-Ciocalteu assay. Data analysis carried out SPSS version 25 triplicate determinations. Mean differences among fruit extracts were One way-ANOVA, while correlations between studied components by Pearson's Correlation Coefficient Test. The a picker software. TEAC values range 332.30 ± 18.04 µg Trolox/g D.W. (avocado leaves) 12217.71 (banana from 10.07 3.89% 86.70 0.26 % leaves).
