Abstract: In this study, silver nanoparticles were produced through biosynthesis method from the methanolic extract of leaves of Zygophyllum Qatarense Hadidi. In this study, the principles of green synthesis were followed. The antifungal properties of nanoparticles were also investigated. The methanolic extract of leaves of Zygophyllum Qatarense Hadidi was used as a stabilizer or capping agent and reducing agent to reduce Ag+ to metallic silver. In the present study, the possibility of producing silver nanoparticles from silver nitrate solution was studied. The results revealed that the obtained nanoparticles had an average diameter of 47 nm. UV-vis spectroscopy and SEM imaging confirmed size, shape and formation of silver nanoparticles. Furthermore, the antifungal activity of silver nanoparticles, Zygophyllum qatarense Hadidi leaf extracts and AgNO3 against Aspergillus niger and Penicillum digitatum was investigated by using Disk diffusion and the micro brath dilution methods. All of the treatment had antifungal activity but Silver nanoparticles comparison to other treatment had a significant effect on the Aspergillus niger and Penicillum digitatum.
