ECO-FRIENDLY SYNTHESIS OF MAGNESIUM OXIDE NANOPARTICLES USING RUELLIA PROSTRATA FLOWER EXTRACT AND EVALUATION OF ANTIMICROBIAL ACTIVITY

Lavanya L. and Ramar P.

Abstract

In contrast to physical and chemical approaches, the plant-mediated route, sometimes known as the “green approach,” has garnered a lot of attention lately for producing metal and metal oxide nanoparticles since it is both environmentally friendly and simple to prepare. Phytochemicals, which have been suggested as capping agents and bio-reductants for the formation of metal nanoparticles, are found in plants. Therefore, the purpose of this study was to use an aqueous extract of Ruellia prostrata flowers to create magnesium oxide nanoparticles (MgONPs). First, the phytochemicals in the flower extract were qualitatively examined. Then, in order to verify the synthesis of MgONPs and ascertain the morphology, shape, and size of the sample, the synthesized MgONPs were assessed using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and UV-visible (UV-Vis) spectrophotometry. According to the findings, monodisperse, cubic-shaped MgONPs with an average size of 65.08 ± 19.38 nm were formed, and they may find use as antibacterial agents. The procedure described here could therefore be improved for the production of MgONPs on a wide scale.
