Chemical Composition and Biological Activities of Annona muricata Linn Extracts: A GC-Based Investigation

The antioxidant and antibacterial activities of methanol fruits, leaf, stem, and root extract of Annona muricata Linn were evaluated on gram-positive and gram-negative bacterial strains; S.aureus, S.bovis, S. pneumonia, and E. coli were evaluated by disk diffusion. The antibacterial activity was done using the agar disk diffusion method. The mos inhibited gram-positive bacteria were S.aureus and S.bovis at minimum inhibitory concentration. In contrast, the most inhibited gram-negative bacteria was Escherichia coli at a minimum concentration of S. pneumonia, which was inhibited at almost every concentration of the methanol extract. The plant fruits, leaf, stem, and root extracts showed antibacterial properties but the methanol extract was more effective as it inhibited a wide range of organisms at varying concentrations. There was a significant difference (P
