Abstract: The aim of the present study was to evaluate the antioxidant potential of Antidesma bunius leaf extracts. Antioxidant activity was evaluated via DPPH scavenging assays. In addition, scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical was used to evaluate antioxidant potential of Antidesma bunius. The leaf extracts of Antidesma bunius showed significant antioxidant effects in DPPH scavenging assays. Likewise, methanol (MeOH) extracts of Antidesma bunius exhibited potent inhibitory activities against DPPH with the corresponding IC₅₀ values of 56.49±3.4 µg/mL, respectively. In addition, the highest DPPH scavenging activity was observed in the ethyl acetate (EASF) fraction with an IC₅₀ value of 136.52 ± 0.03 µg/mL, followed by the CH₂Cl₂ fraction (DCMSF) with an IC₅₀ value of 202.60 ± 0.09 µg/mL compared to ascorbic acid (IC₅₀ = 43.04 ± 0.01 µg/mL). Our study establishes that Antidesma bunius extract might be useful as a potential antioxidant agent.
