Chemical composition and antioxidant activity of the pulp, leaves and seeds of soursop Annona muricata L

Abstract:

Soursop Annona muricata L. is a tropical fruit of current interest for its medicinal properties. The compared proximal composition and antioxidant activity of the pulp, fresh and dried leaves, and seeds of soursop were compared. The highest contents of protein (14.77g/100g) and fat (25.75g/100g) were found in seeds. The pulp showed the highest moisture (86.32g/100g) and dry leaves the highest ash (7.17g/100g) content. The antioxidant activity of the studied fractions was higher in ethanolic extracts than methanolic extracts, as also were flavonoid and polyphenol contents. The highest values of antioxidant activity in ethanol extracts were 306.0, 280.2 and 131.2μmoles Trolox equivalents/100g in the pulp, dried leaves and seeds, respectively. Soursop pulp had the highest contents of flavonoids (574.0mg QE/100g) and polyphenols (941.4mg AGE/100g).
