Green fabrication of Piper betle leaf extract assisted magnesium oxide nanoparticles with antioxidant potential

Abstract The combination of Biotechnology and Nanotechnology is called as Bio-nanotechnology. Bio-nanotechnology is generally used to create nanomaterial utilizing biological method. In this paper, MgO nanoparticles were produced by utilizing extract of Piper betle leaf as bio-reducing agent. By employing the standard techniques namely UV-Visible spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive analysis and thermogravimetric analysis to find out the physio chemical properties of green synthesized MgO NPs. All the outcome shows that the produced particles were spherical shape in the range of 18–20 nm, crystalline nature. The antioxidant activity of P. betle assisted MgO NPs were performed using DPPH assay. The DPPH assay of P. betle assisted MgO NPs could reach 88% at a concentration of 500 µg/ml, respectively. From the outcomes it was determined that the P. betle assisted MgO NPs have good antioxidant properties.
