Many species of Eucalyptus are used as a folk medicine. Traditionally, they are used in the treatment of many respiratory tract infections like bronchitis, sinusitis and pharyngitis as it is rich with the antimicrobial inhibitory agent. The present study aimed to determine the phytochemical and bioactivity of commercially available Eucalyptus oil against human pathogens which cause many infections in human population. The “AXE Brand Eucalyptus oil” which are used for the relief of colic and stomachache show significant bioactivity against Staphylococcus aureus, Escherichia coli, Salmonella paratyphi A, Salmonella paratyphi B, Shigella dysenteriae, Bacillus licheniformis and Pseudomonas aeruginos, which is seen as a significant pathogen. However, Highest bioactivity observed against Bacillus licheniformis whereas no activity or zeroes zone of inhibition shows against Bacillus subtilis and Salmonella typhi. Phytochemical tests to know about the secondary metabolites show the presence of phytosterols, phenols, tannins, flavanoids, protein and amino acid. On the bases of this result, the oil of eucalyptus can be effectively utilized in the treatment of infectious disease as well as in Sanitizers and disinfectant as an innate and environmental friendly product.
