Acacia auriculiformis is an important medicinal plant and distributed throughout India. It is used as a folk medicine against derm diseases, diarrhea and fever. In the present study, ethanolic extract was prepared from Acacia auriculiformis and it was used to screen for phytochemical analysis, antimicrobial and antioxidant properties. Antimicrobial activity was carried out by using three bacterial strains such as Staphylococus aureus, Pseudomonas aeruginosa, Bacillus subtilis and two fungal species such as Aspargillus niger and Candida albican. This ethanolic extract showed highest antibacterial activity against Pseudomonas aeruginosa (19.54±0.4) and as staphylococcus aureus (18.28±0.47). In contrast, it showed moderate activity against Bacillus subtilis (14.68±0.47). Whereas ethanolic showed best antifungal activity against Aspargillus niger (20.62±0.17) and ethanolic extract showed low antifungal activity against Candida albican (9.62±0.92) at highest concentration 100mg/ml concentration. The ethanolic extract showed better free radical scavenging (antioxidant) activity at all concentrations. Our results clearly reveal that the ethanolic extract of Acacia auriculiformis showed high content of phytochemicals, good antimicrobial and antioxidant activity and our results supporting the usage of the plant Acacia auriculiformis as folk and traditional medicine.
