Green Synthesis of Silver Nanoparticles from Astragalus Lagopoides L. Leaves

Natural products have gained great interest due to their broad spectrum of biological activities. In this study, silver nanoparticles (AgNPs) were synthesized using Astragalus lagopoides L. by green approach. The structure of AgNPs was elucidated by spectroscopic techniques. UV-Vis spectrum presented the maximum absorption of AgNPs at 419 nm. The crystal structure of AgNPs was assigned as face centered cubic by X-ray diffraction (XRD) pattern. Scanning electron microscope (SEM) established morphology of AgNPs with an average size of 36.4 nm. A. lagopoides included the bioactive compounds, So, AgNPs capped by these compounds could be valuable substances for food and pharmaceutical applications.
