Flower-Mediated Phytosynthesis of Silver Nanoparticles from Butea monosperma Lam. and their Evaluation for Antibacterial Activity
The green synthesis of metallic nanoparticles is the simplest, affordable and eco-friendly approach, which attracted researchers because of their immense applications. The plant-mediated synthesis of nanoparticles plays an important role in the field of nanobiotechnology as they devoid of harmful chemicals. Plenty of reports were available on synthesis of silver nanoparticles using the vegetative parts of plant especially foliar/leaf parts but reports on floral/flower parts utilized for silver nanoparticles synthesis were limited. Although flowers were found as potential source of many important phytochemicals which can be used for treatments of many diseases and Butea monosperma Lam. Flowers were utilized for curing several diseases so, here its extract were used for synthesis of silver nanoparticles by using it as capping and stabilizing agent. The present study, deals with synthesis of silver nanoparticles (AgNPs) from Butea monosperma Lam. Flower extracts through greener approach and then synthesized AgNPs were characterized using UV- visible spectrometry, X-Ray diffraction (XRD), Fourier transform infra-red (FTIR) spectroscopy and Scanning electron microscopy (SEM) which confirms its synthesis from silver metal. Further, the anti-bacterial properties of the synthesized silver nanoparticles were studied, and the results revealed that the flower mediated silver nanoparticles had showed strong anti-bacterial activity against Pseudomonas sp., Escherichia coli, Bacillus subtilis and Staphylococcus aureus.
