Abstract
The jamun fruit, Syzygium cumini, is known for its significant antioxidant and antigenotoxic characteristics in addition to its antidiabetic effects. Although numerous plant parts are utilized in herbal preparations, the chemical makeup of the fruit and seed is little understood. The high phenolic content of the seed was recently reported. In this study, zinc oxide nanoparticles (ZnO NPs) from Syzygium cumini are synthesized, characterized and evaluated for their antioxidant characteristics (SC). SC seed extract was used to make ZnO NPs which were then studied using X-ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy and Ultraviolet-visible spectroscopy. Several doses of nanoparticles were used in antioxidant assays such as the reducing power assay, the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and the hydrogen peroxide assay. It was discovered that the antioxidant activity increased along with the NP content.
