Acacia nilotica, Aedes albopictus, Aluminium chloride assay, Antimicrobial activity, FRAP assay, mosquito larvicide bioassay


In the present study fruit of Acacia nilotica was chosen to evaluate its antioxidant, larvicidal and antibacterial properties. Phytochemical screening of aqueous and alcohol extracts of the plant fruits affirmed the presence of carbohydrates, reducing sugar, phenol, flavonoid, terpenoid, saponin and steroid. The antioxidant properties of the aqueous and alcohol fruit extracts were noted as 10.11±0.035 and 9.75±0.023 mM of FeSO4 for Ferric Reducing Antioxidant Power (FRAP) assay respectively. The potency of antimicrobial activity of the aqueous and alcohol extract of A. nilotica fruit were tested against Pseudomonas aeruginosa, Staphylococcus aureus, Bacillussubtilis, and Escherichiacoli. The alcohol extract against E. coli, exhibited the highest antimicrobial activity. Aqueous extracts of A. nilotica fruit showed potential toxicity against Aedes albopictus larvae with LC50 value of 142.074 mg L-1. Present findings clearly indicated that A. nilotica fruit extracts could be most effectively used as a natural antioxidant, antibacterial and larvicidal agent.
