Comparative Study on Chemical Composition and Antioxidant Activity of Annona Muricata Plant Parts Cultivated in Covenant University, Ota, Ogun State, Nigeria

Annona muricata plant parts possess a broad range of medicinal and biological properties. This research compared the chemical composition and antioxidant properties of Annona muricata parts. Proximate, mineral, total phenol and total flavonoid content as well as in vitro antioxidant activity were examined. Results revealed the leaves contained significantly (p<0.05) higher composition of moisture (8.69±0.22 %), ash (4.60±0.02 %), protein (14.53±0.11 %), crude fat (10.28±0.03 %), chromium (0.38±0.05 mg/100g), nickel (1.75±0.04 mg/100g), total phenol (1.01±0.03 mg pyrocatechol/mL) and total flavonoid (1.12±0.03 mgGAE/mL) compared to the respective values for root. Carbohydrate (9.29±0.24 %), lead (0.13±0.02 mg/100g) and cobalt (1.93±0.02 mg/100g) composition was significantly lower (p<0.05) in the leaves compared to the respective compositions in the root. The leaf and root extract exhibited a concentration-dependent increase in hydroxyl radical scavenging activity with no observable (p
