- ABSTRACT Present study, we utilized the bio–reductive potential of the plant leaf essential oil Rosemarinus officinalis, for the synthesis of silver nanoparticles (AgNPs). The green synthesized AgNPs was achieved at 80°C and found to be highly stable in room temperature for some time. The AgNPs was found to be small dot round in shape with an average size of ~52nm in diameter. The AgNPs were characterized using ultraviolet-visible absorption spectroscopy fourier transform Infrared spectroscopy (FTIR), transmission electron microscopy (TEM),Scanning electron microscopy and Edx (SEM). The anti-fungal activities of the synthesized AgNPs were tested against a few human fungal pathogens Aspergillus niger, Aspergillus flavus, Candida albicans, Candida tropicalis and Candida kefyr showed high activity against these microorganisms. The results showed that the size and the shape can be easily controlled by employing the optimum concentrations ratio of AgNO3 solution and also varying temperature and incubation time. The synthesized AgNPs from Rosemarinus officinalis plant leaf oil can be used as a potent therapeutic agent and for anti-cancer activity.
