In recent years, metal nanoparticles are of scientific interest due to their properties, among which are optical, electrical, magnetic and high surface. In this work, a green, ecological and affordable synthesis of silver nanoparticles (AgNPs) using an alcoholic extract of Porophyllum ruderale leaves. The AgNPs obtained were characterized by IR spectroscopy to observe the formation of the carboxyl and rupture of hydroxyl that intervene in the synthesis mechanism. UV-Vis spectroscopy was used to study the surface plasmon band, confirming the peak absorbance wavelength at 385 nm. The morphological analysis by SEM showed AgNPs measuring 70-500 nm and spherical shapes. The optimal factors for AgNPs formation were found to be 100 ºC temperature and 1:3 ratio. The work proved that by green synthesis using plant, metal ions such as Ag can be reduced and the AgNPs can be potentially applied as biosensors and antimicrobial agents, among others.
