The flower extract acted both as a reducing as well as a capping agent.</p><p><strong>Methods: </strong>Silver nanoparticles were verified using various spectroanalytical techniques such as visible ultraviolet spectroscopy, zeta potential, fourier transform infrared spectroscopy and particle size analyser. The antibacterial activity was evaluated against both the gram-positive bacteria <em>S. aureus</em> and gram-negative bacteria <em>E. coli </em>using the agar well diffusion method.<em></em></p><p class="Normal1"><strong>Results: </strong>The silver nanoparticles<em> </em>synthesized were confirmed by the visual colour change. The ultraviolet, visible spectroscopy showed a surface plasmon resonance at 430 nm. Zetapotential was found to be around-15.6mV where the negative value indicated that the synthesized silver nanoparticles are stable. Fourier transform infrared spectroscopy showed the functional groups responsible for the stabilization of the nanoparticles. Particle size analyser showed that the size of the nanoparticles ranged from 5-50 nm. The antibacterial activity of the silver nanoparticles which was performed against <em>S. aureus</em> and <em>E. coli</em> showed good inhibition against both the bacteria. Better antibacterial activity was found for <em>E. coli</em> in comparison to <em>S. aureus</em> as the zone of inhibition for<em> E. coli </em>was found to be at 12 mm at 50ug/ml whereas the zone of inhibition against <em>S. aureus </em>was found to be at 10 mm.</p><p><strong>Conclusion: </strong>The silver nanoparticles were successfully synthesized using a green approach and can be used as a potential resource for therapeutic purpose.</p> ER -
