Isolation and Characterization of Extracellular Vesicles Derived from Mango Fruits

The mango (<i>Mangifera indica</i> L.) is a commonly cultivated tropical fruit across the globe. It is known to be rich in carotenoids, polyphenols, and vitamins, compounds that largely account for its nutritional and medicinal properties. Although the beneficial effects of mango phytochemicals have been widely documented, virtually no studies have investigated extracellular vesicles (EVs) originating from mango fruit. In the presented work, we developed a workflow combining differential centrifugation, filtration, and size-exclusion chromatography for the isolation of EVs from mango pulp. The isolates were characterized in accordance with the guidelines of the International Society of Extracellular Vesicles recommendations. The optimized size-exclusion chromatography column, packed with Sepharose CL-6B beads, enabled the recovery of a high-quality EV fraction, which was characterized in terms of physicochemical properties. Additionally, proteomic analysis identified 1084 proteins, many of which are associated with antioxidant, antimicrobial, and anti-inflammatory functions. These findings provide the first comprehensive characterization of mango-derived EVs and suggest that they may contribute to the biological activity traditionally attributed to mango consumption.
