Characterization and quantification of bioactive compounds and antioxidant activity in three different varieties of mango (Mangifera indica L.) peel from the Ecuadorian region …

Abstract:

Mango peel is gaining recognition for its nutritional and functional value. This by-product shows variable composition depending on different factors such as variety, stage maturity, and geographic site of production. This work sought to evaluate mango peel composition, bioactive compound content, antioxidant activity, and carotenoid and phenolic profiles for the three most commercial varieties of the equatorial region using UV–Vis spectroscopy, HPLC, and UPLC. Significant differences (p < 0.05) were found between all varieties regarding the content of bioactive compounds. Total phenolic, flavonoid, and carotenoid content ranged from 2930 to 6624 mg GAE/100 g, 502–795 mg CE/100 g, and 3.7–5.7 mg/100 g, respectively. A high positive correlation (r = 0.961) between the phenolic content and ABTS radical-scavenging activity was found for all samples. β-Carotene and lutein were identified and quantified, the …
