Abstract

• The biological method to synthesize magnesium oxide nanoparticles with therapeutic and medicinal potential is a significant challenge in nanotechnology. In this study, to examine the efficacy of the aqueous leaf extract of Oroxylum indicum as stabilizing agents, they were mixed with MgSO4.7H2O (Epsom salt) precursor solution, followed by NaOH solution to form a precipitate of magnesium hydroxide. Then, the precipitates were calcined for 5 h, to synthesize MgO NPs. Modern techniques such as XRD, SEM-EDX, FT IR, Raman, UV-visible and TG-DTA were employed to characterize the synthesized MgO NPs. The produced nanoparticles were identified as pure MgO with a cubic structure and a spherical in shape, and ranged in size from 16 to 21 nm. Furthermore, this study has reported that the synthesized MgO NPs have excellent bioactivities (antioxidant, antidiabetic, and anti-inflammatory) and revealed good results for biomedical applications.
