BAU K ul ( Z iziphus mauritiana) is a new and improved variety of plum fruit from B angladesh. This study aims to investigate the antioxidant potency and antibacterial activity of methanolic extracts of BAU K ul using S oxhlet extraction followed by complete evaporation of residual methanol. BAU K ul is a very good source of phenolics, flavonoids, ascorbic acid and tannins. The reducing sugar and protein content of BAU K ul were 1.68 and 0.81% by weight, respectively. BAU K ul was very active in 1,1‐diphenyl‐2‐ picrylhydrazyl radical (DPPH) scavenging and ferric reducing antioxidant power assay (527.28 ± 9.2 [μ M F e ( II )]/100 g), thus confirming its high antioxidant potential. Antibacterial activities were measured using the agar well‐diffusion method. BAU K ul was most toxic to P seudomonas aeruginosa , followed (in order) by S taphylococcus aureus , S almonella paratyphi , E scherichia coli and C hromobacterium violaceum . In conclusion, BAU K ul is a nutritious fruit that provides good antioxidant and antibacterial activities (in particular toward P . aeruginosa ) and a cheap source of vitamins. Practical Applications BAU K ul is a new and sweet seasonal fruit which is very popular to the consumers of B angladesh. This fruit can be a good source of nutrients as well as the antioxidants applicable in different types of diseases caused by oxidative stresses. BAU K ul can also be used as traditional medicine for different types for infectious diseases.
