Nanomaterial is those their size ranges between 1 nm to 100 nm. Currently due to their many applications uses, nanomaterial made from metal oxide through phytochemical extracts of plant leaves are in high demand. Therefore, in this work the researcher focused on ZnO nanoparticles by solution-burning an aqueous extract of Croton macrostachyus, leaf plant. Hence secondary metabolites of Croton macrostachyus, including flavonoids, tannins, and phenolic chemicals, may aid in the decrease, settling down, and sealing of nanoparticles during this phyto-mediated synthesis. This study used the precursor Zn (CH3COO)2.3H2O to synthesize ZnO nanoparticles. Powder X-ray diffraction, Fourier Transform Infrared, UV-visible, and UV-visible diffuse reflectance, X-ray photoelectron, Transmission Electron Microscopy, Scanning Electron Microscopy with energy dispersive X-ray, and a high-resolution transmission electron microscope were used to characterize the synthesized samples. The scavenging activity of DDPH, ZnO nanoparticles showed less than ascorbic acid, as concentration of the sample increased the scavenging activity was increased. ZnO nanoparticles' optical band gap energy was 3.20 eV.
