Green synthesis of silver nanoparticles (AgNPs) was performed using extracts from Ornithogalum narbonense L. (ONL) as a cost-effective and eco-friendly approach. A surface plasmon resonance peak was observed at 440 nm after 12 h. The intense reddish-brown coloration was observed higher than 1.5 mM AgNO3 concentrations. Bioactive compounds were found responsible for the reduction, stabilization, and capping of Ag+ to AgNPs. X-ray powder diffraction analysis confirmed the face-centered cubic silver crystalline structure. The average spherical-shaped individual particle size was around 8.46 nm, while hydrodynamic size ranged between 7–13 nm and 36–131 nm. The AgNPs have good stability (ζ = –31.15 mV). Energy-dispersive X-ray spectroscopy analysis proved the presence of elemental Ag (6.76%). The antibacterial activity with the zone of inhibition is as follows: P. aeruginosa > E. coli > S.aureus > B. cereus (10.35 ± 0.12 mm > 9.40 ± 0.14 mm > 8.20 ± 0.10 mm > 7.0 ± 0.24 mm). The AgNPs did not show antifungal properties against C. albicans.HIGHLIGHTS The aqueous extract of Ornithogalum Narbonense L was used for the green synthesis of AgNPs. XRD, SEM, EDX, FTIR, ζ-potential, DLS and UV-vis characterizations were made. The average surface charge and diameter of individual AgNPs were determined as –31.15 mV and 8.46 nm. AgNPs acted as an inhibitor toward E.coli, P.aeruginosa, E.faecalis, S.aureus and B.cereus.
