Abstract: This study describes the antioxidant, antibacterial activities of five different solvents [methanol, aqueous ethanol (ethanol-water, 70:30, v/v), acetone, ethyl acetate and water extracts of Passiflora wilsonii Hemsl. The results obtained in this study have considerable value with respect to various solvent extracts from Passiflora wilsonii Hemsl., showed varying degrees of antioxidant activity in different test systems in a dose-dependent manner. All solvent extracts of Passiflora wilsonii Hemsl. exhibited scavenging activities toward 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) diammonium salt (ABTS), superoxide anion and hydroxyl radicals. On the other hand, the ethanol fraction showed the highest antioxidant and antibacterial activities in most instances. This study verified that the ethanol extract have strong antioxidant and antibacterial activities which were correlated with its high level of flavonoids.
