Objectives: The primary focus of this study is to present antibacterial and anti oxidant efficacy of Silver nanoparticles (AgNPs) synthesized from the aqueous leaf extract of Sechium edule (S. edule) plant by ultrasonication assisted method.

Methods: Silver nanoparticles were synthesized by ultrasonic assistance using aqueous leaf extract of Sechium edule (S. edule) as a reducing agent. Characterization of AgNPs was done by UV-Visible spectroscopy, FTIR, SEM and TEM. Antibacterial activity was analyzed by using disc diffusion method and 2, 2- Diphenyl 1- picryl hydrazyl (DPPH) scavenging assay for antioxidant evaluation.

Results and Discussion: Visual observation of brown color indicated the formation of AgNPs. Further confirmation was done by using UV-Visible, FTIR spectroscopy. Morphological analysis by SEM and TEM technique indicated the triangular pyramidal shape with 10 nm in size.

Conclusion: Results obtained suggest that AgNPs from aqueous extract of Sechium edule leaf extract show enhanced antibacterial and antioxidant efficacy.
