The aim of this work is a green synthesis of gold nanoparticles using the aqueous extract of Anthriscus sylvestris, Ferula gummosa, and Achillea eriohora leaf and stems as the reducing agents. The effects of reducing agent concentration in the reaction mixture and temperature on the size of the gold nanotriangles were studied. The nanoparticles were characterized using UV–Vis spectroscopy, XRD, and SEM. XRD studies show that the particles are crystalline in the cubic phase. However, the reduction of gold ions by plant extracts resulted in the formation of spherical gold nanoparticles with diameters from 18 to 56 nm.
