Identification and quantification of phenolic compounds in African bush mango (Irvingia wombolu) fruit, free-radical scavenging activity and the nutritive values of its peel and pulp extracts


Catherine Joke Adeseko

The phenolic constituents, Proximate, vitamin (A and B), and mineral compositions of wild of African bush mango (Irvingia wombolu) fruit (peel and pulp) were evaluated. Their total phenolic, flavonoids, (TAC), FRAP, DPPH, NO, OH-, and lipid peroxidation radical scavenging activity were also determined. Samples were analyzed using standard procedures for all determinations. Concentrations of minerals such as iron, copper, potassium, zinc and manganese were higher in peel than pulp. The peel and pulp of I. wombolu showed almost similar pattern of scavenging activities. The IC50 showed that the peel extract has a higher free radical scavenging activity than pulp. The proximate, vitamin A and B compositions, concentrations of antinutrients (oxalates, phytates and tannins), and the quantity of the identified phenolic compounds from the fruit of I. wombolu were higher in peel than pulp. However, the peel and pulp extracts of I. wombolu fruit could significantly impact the health of populace if properly harnessed and utilized.
