Several bioreduction processes become appreciation for the synthesis of silver nanoparticles (AgNPs) because of their multiple applications, cost effective and eco-friendly. The main problems in the synthesis of AgNPs are colloidal systems agglomeration and damage due to precipitation. In this study,it has been investigated the use ofUncariaGambirRoxbleaf extract as bioreductorand capping agent on the synthesis of AgNPsand isopropanol as a solvent. XRD studies showed that the AgNPsare crystalline fcc (face center cubic) without another phase and AgNPs size in isopropanol solution was smaller than aqueous solution. TEM images indicated that the obtained AgNPs are predominantly spherical shape, with sizes in the range of 10 to 30nm.
