| dc.description.abstract | Traditionally the outermost parts of most fruits are peeled off and discarded as waste which can constitute environmental pollution. To reduce this, the society must be made to see the value of these parts that are traditionally discarded. This is the basis of this study aimed at investigating the preliminary phytochemical screening, antioxidant properties and mineral composition ofthe ethanol extract ofAnnona muricata pulp, peel and seed using standard procedures. The results showed the presence of tannins, phenols, steroids, glycosides, terpenoids, alkaloids, flavonoids, resins, carbohydrates and phlobatanins in the pulp. In the peel, tannins, steroids, glycosides, phenols, alkaloids, flavonoids, resins, carbohydrates, phlobatanins and balsams were present while steroids, saponins, terpenoids, flavonoids, volatile oils, carbohydrates, phlobatannins and balsams were present in the seed At highest concentration of 2 g/ml the pulp had 80.049±0.004% free radical scavenging ability; the peel had 86.797±0.001% while the seed had 77.586±0.002% while ascorbic acid had 54.433±0.001%. The result showed Fe concentration of 0.0138±0.0002 g/ml in the pulp, 0.1449±0.0001 g/ml in the peel and 0.0170±0.0002 g/ml in the seed. Mg concentration was 0.4999±0.0008 g/ml in the pulp, 0.8069±0.0009 g/ml in the peel and 0.7155±0.0002 g/ml in the seed, Cu was 1.0050±0.0002 g/ml in the pulp, 0.0044± 0.0009 g/ml in the peel and 0.0078± 0.0009 g/ml in the seed while Ca was 0.0309±0.0001 g/ml in the pulp, 0.6959±0.0002 g/ml in the peel and 0.3427±0.0016 g/ml in the seed. These results showed that the peel, pulp and seed were rich in phytochemical, mineral nutrients and antioxidant properties, hence the need to encourage their utilisation for pharmacological and nutritional us | |
