- Abstract
- Facile approach to synthesize the metal oxide nanoparticles is getting an increased attention in various biomedical applications such as, to treat antibiotic resistant diseases. Magnesium oxide nanoparticles (MgO center dot NPs) were synthesized by using Clitoria ternatea as the stabilizer in a green synthesis approach. The preliminary screening of MgO center dot NPs in the presence of C. ternatea extract was observed by UV-visible spectrophotometer. X-ray diffraction (XRD) pattern have proved the crystalline nature of the MgO center dot NPs; Photoluminescence (PL) measurement studies are used to identify the quality and defects in the crystal structure. FE-SEM with EDS has showed the size of 50-400 nm with specific binding energies. FT-IR has revealed the functional groups present in the plant extract and the peak at 521 cm(-1) indicated the characteristic absorption bands of MgO center dot NPs. The DPPH activity and reducing power assay of biologically synthesized MgO center dot NPs could reach 65 % at a concentration of 150 mu g/ml, respectively. From the results it was concluded that the biologically synthesized MgO center dot NPs exhibit good antioxidant activity.
