摘要：

The synthesis of nanoparticles by green chemistry offers a method that respects the environment. The experimental conditions and the existing interactions between the reducing agents in Cupressus goveniana extract and the Au+3 ions have a directly influence in the size, morphology and stability, as well as the physicochemical properties of the particles. Is possible consider he formation of AuNPs in the change of color of the extract when adding the precursor agent and by UV-Visible spectroscopy, indicating a plasmon of absorbance characteristic of this metal. The extract was characterized by FTIR, and to evaluate the reductive capacity of Cupressus goveniana extract, a cyclic voltammetry was carried out, for which the reducing capacity of the Au+3 ions is attributed to obtain the AuNPs.
