Phytochemical profile and antioxidant properties of the edible and non-edible portions of black sapote (Diospyros digyna Jacq.)

2022

This study evaluated the phytochemical profile and antioxidative properties of the edible and non-edible portions of black sapote. The phytochemical analysis highlighted the presence of several bioactive compounds, differently distributed among peel, pulp and seeds. In particular, the peel resulted rich of flavan-3-ols and proanthocyanidins, whereas seeds contained high amount of organic acids, including ferulic, citric and sinapic acids. Concerning functional properties, both edible and non-edible portions showed a significant prevention of lipid peroxidation in a cell-based model. Moreover, the results suggested that the antioxidant protection involved both redox active properties and gen…
