Antimicrobial activity was determined by disc diffusion method. Results: GCeMS analysis showed the presence of fatty acids, aliphatic, aromatic and phenolic acids. The antioxidant activity of immature fruit and leaf extracts yielded high activity when compared to the fruit skin. The fruit skin and immature fruit of <em>C. urens</em> exhibited strong antibacterial activity against the tested pathogens (<em>Escherichia coli,</em> <em>Vibrio cholerae, Salmonella typhii, Staphylococcus aureus</em> and <em>Shigella flexneri</em>) when compared to leaf. <strong>Conclusion:</strong> In our results, we suggest that <em>C. urens</em> extracts have strong antioxidant and antimicrobial potential. The identified bioactive compounds of<em> C. urens</em> could be attributed to antioxidant and antimicrobial property.</p> ER -
