Due to the potential applications in the expansion of nanotechnologies synthesis of zinc oxide nanoparticles (ZnO-NPs) became a expanding area of research. In the present research work, we described a low cost, eco friendly and simple method for the green synthesis of ZnO-NPs using stem extract of Rubia cordifolia. The structural and morphological properties have been characterized by XRD, SEM, EDX and TEM analysis. Synthesized NPs are hexagonal wurtzite structure with an average size 20.07 nm was obtained from XRD and they are spherical in shape. The applications of ZnO-NPs exhibit potential anti oxidant activity depend upon concentration of synthesized ZnO-NPs and photocatalytic activity towards degradation of methylene blue dye depend upon time exposure in the sunlight irradiation.
