Here, major components of Rosemary (Rosmarinus officinalis L.) leaf extracts were isolated monthly during 2012-2013 and their competences for Ag–conjugated nanoparticle biosynthesis were studied. Formation of Ag/AgCl–NPs was examined using UV-visible spectroscopy and characterized by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), and Transmission electron microscopy (TEM). Correlation analysis showed that extracts with more protein contents and higher total reducing capacity were more efficient in biosynthesis of Ag/AgCl–NPs. There existed no correlation between total phenolic, ascorbic acid and anthocyanin contents with Ag/AgCl–NPs biosynthesis activity. These results partly explain the mechanisms controlling plant mediated biosynthesis of nanoparticles, with possible applications in standardization of plant materials harvested throughout a year.}, keywords = {Ag/AgCl–NPs Biosynthesis,Antioxidant Activity,FTIR,nanoparticles,Rosmarinus Officinalis}, url = {https://www.ijnnonline.net/article_33279.html}, eprint = {https://www.ijnnonline.net/article_33279_cd7dd8b934c4f44fa34f5e7e93287a44.pdf} }
