Síntese verde de nanopartículas de zinco funcionalizadas com a fração orgânica acetato de etila das folhas de Maytenus Ilicifolia Mart. Ex Reissek

Abstract

The study addresses the green synthesis of functionalized zinc oxide nanoparticles with the organic ethyl acetate fraction obtained from the partition of Maytenus leaf extract Ilicifolia (ZnNPs-Mi). The characterization of ZnNPs-Mi was carried out using spectroscopy Ultraviolet-Visible (UV-Vis), Fourier Transform Infrared Spectroscopy (FT-IR), Dynamic Light Scattering (DLS), Zeta Potential and methods to determine the in vitro antioxidant potential of ZnNPs-Mi, by eliminating 2,2-diphenyl 1-picrylhydrazyl (DPPH) free radicals, ferric reducing antioxidant potential (FRAP) and capacity to oxygen radical absorption (ORAC). The UV-Vis spectra showed absorption peaks at around 450 nm due to the high binding excitation energy. FT-IR Analyzes confirmed chemical bonds in zinc oxide, while DLS revealed the size of the nanoparticle at 967 nm. The Zeta Potential was -5.83 mV, demonstrating the presence of FAE Mi as a coating layer on the nanoparticles. Potential analyzes antioxidant revealed that ZnNPs-Mi possessed antioxidant effects. With that, it was addressed a more sustainable and economical project with potential for biomedical and agricultural.
