N2 - In this work, gold nanoparticles (AuNPs) were synthesized from extracts of Agave potatorum leaves using three solvents with different polarities (water, ethanol, and hexane) for the extraction of phytochemicals from the biomass of Agave potatorum. The different biosynthesized nanoparticles were microstructurally characterized using UV–Vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy lower secondary electrons (LEI-SEM), and X-ray diffraction (XRD). UV–Vis spectra analysis revealed clear surface plasmon resonance (SPR) signals close to 540 nm showing differentiation according to the metabolites present in the extract used, as well as TEM micrographs showing different average sizes of nanoparticles according to the extract used, and XRD results provided evidence of the metallic character of the synthesized nanoparticles. The results showed a strong relationship between synthesis times, crystallinity, and the metabolites in each extract.
