Recently, the focus has been on the environment-friendly synthesis of nanoparticles (NPs) due to no chemical processing and generation of toxic and hazardous materials. Here, a novel method has been reported for the synthesis ofcerium oxide nanoparticles (CeO$_2$ NPs) through a green route using Dillenia indica aqueous extract. The physicochemical properties and morphological study of CeO$_2$ NPs were performed by using X-ray diffraction, field-emissions canning electron microscope imaging, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, RAMAN and ultraviolet-visible spectra. The nano-polycrystallinity of face cubic lattice structure is formed in CeO$_2$ NPssamples with an average particle size of 70 nm. The anti-oxidant property study of CeO$_2$ NPs was carried out using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay. The CeO$_2$ NPs assure significant DPPH scavenging activity indicating excellent anti-oxidant property. This green synthesis method has the potential for mass production of CeO$_2$ NPs cost effectively without environmental pollution.
