Objective: The objective of the present study aimed at investigating the phytochemical antioxidant and anti-microbial properties of Carica papaya leaf extracts. Methods: As phytochemicals are biologically active compounds and a powerful group of plant chemicals believed to stimulate the immune system along with antioxidants, the molecules which hinder oxidation of other molecules by the process of inhibiting or by generating the oxidizing chain reactions and preventing diseases. The anti-microbial activity on various gram-positive and gram-negative bacteria were determined using zone of inhibition and antioxidant by the 2,2,1-diphenyl-1-picrylhydrazyl method. Results: Phytochemical screening, antioxidant and antibacterial potential were determined using different aqueous and organic solvents in addition to the determination of trace element in leaves of C. papaya. Antioxidant activity using DPPH free radical scavenging assay indicated leaves extracts leaves showed inhibition of per oxidation. The result showed that the ethanolic extract of C. papaya possessed a significant antioxidant activity as compared to methanol and aqueous extract. The antibacterial study showed leaves extract is the best to cope infectious action of bacteria. Conclusion: This study was conducted to test the medicinal profile of C. papaya by extracting secondary metabolites with organic and aqueous solvents. Ethanol was found to be the best solvents of choice to extract natural products to get maximum medicinal benefits and could be used to medicinal formulation against different infectious diseases.
