Green Synthesis of Silver Nanoparticles Using Murraya koenigii Leaf Extract and Their Antibacterial Potential

Abstract

The eco-friendly and green synthesis of silver nanoparticles (AgNPs) was done by using the extract of young leaves of medicinally important plant Murraya koenigii (Curry Leaves). This method was very simple and rapid multiplication. The green synthesized silver nanoparticles were characterized by FTIR and X-ray diffraction (XRD). To identify the compounds responsible for reduction of silver ions, the functional groups present in plant extract were investigated by FTIR analysis and to observe the crystalline nature, structure was analyzed in XRD. Antibacterial activity of Ag NPs was performed by disc diffusion method against E. coli, Bacillus subtilis, Klebsiella pneumonia, Enterococcus faecalis and Staphylococcus aureus. The highest antimicrobial activity of silver nanoparticles synthesized by Murraya koenigii extracts was found against Klebsiella pneumoniae (20 mm). The result revealed that the plant has potent antibacterial activity and it can be used in drug preparation in future.
