Chemical Composition, Total Phenolic Content, and Antioxidant Activities of the Essential Oils of the Leaves and Fruit Pulp of Annona muricata L. (Soursop) from Ghana

Table 4

DPPH free radical and hydrogen peroxide scavenging activities of essential oils and hydrosols from leaf and fruit pulp of Annona muricata.

Sample	IC50 (μg/mL)	% H2O2 scavenged
Pulp essential oil	512.0 ± 5.1	24.38 ± 0.21
Leaf essential oil	244.8 ± 3.2	31.80 ± 0.51
Ascorbic acid	21.3 ± 3.2	ND
Gallic acid	ND	95.00 ± 1.12

IC₅₀, concentration of extract required to scavenge 50% of DPPH radicals. % H₂O₂ scavenged was determined at 1 mg/mL for essential oils. For gallic acid, % H₂O₂ scavenged was determined at 50 μg/mL.
