“…The breakdown of cell membranes is a proposed method for antibacterial action. Numerous approaches, notably sol-gel [9], sonochemistry [10], co-precipitation [11,12], and chemical oxidation [13], have been used to make MgO NPs. Water solutions or extraction from plants are the examples of green synthesis approaches that involve chemicals that are totally void of compounds that are environmentally damaging [14,15].…”

The use of F. religiosa might be beneficial in inflammatory illnesses and can be used for a variety of health conditions. In this article, we studied the identification of antioxidants using (DPPH) 2, 2-Diphenyl-1-picrylhydrazylradical scavenging activity in Ficus religiosa, as F. religiosa is an important herbal plant, and every part of it has various medicinal properties such as antibacterial properties that can be used by the researchers in the development and design of various new drugs. The 2, 2-Diphenyl-1- picrylhydrazyl (DPPH) is a popular, quick, easy, and affordable approach for the measurement of antioxidant properties that includes the use of the free radicals used for assessing the potential of substances to serve as hydrogen providers or free-radical scavengers (FRS). The technique of DPPH testing is associated with the elimination of DPPH, which would be a stabilized free radical. The free-radical DPPH interacts with an odd electron to yield a strong absorbance at 517 nm, i.e., a purple hue. An FRS antioxidant, for example, reacts to DPPH to form DPPHH, which has a lower absorbance than DPPH because of the lower amount of hydrogen. It is radical in comparison to the DPPH-H form, because it causes decolorization, or a yellow hue, as the number of electrons absorbed increases. Decolorization affects the lowering capacity significantly. As soon as the DPPH solutions are combined with the hydrogen atom source, the lower state of diphenylpicrylhydrazine is formed, shedding its violet color. To explain the processes behind the DPPH tests, as well as their applicability to Ficus religiosa (F. religiosa) in the manufacture of metal oxide nanoparticles, in particular MgO, and their influence on antioxidants, a specimen from the test was chosen for further study. According to our findings, F. religiosa has antioxidant qualities and may be useful in the treatment of disorders caused by free radicals.

“…In the context of MgO production, seawater is an attractive raw material as this unlimited natural resource contains Mg 2+ at 1265 [25], 1290 [26], or 1600 ppm [27] and is the second most abundant cation after Na + . A previous study reported the production of MgO from seawater and bittern by using an electrochemical method [28]. The purity of MgO produced from seawater and bittern demonstrated purity in the range of 77.33%-92.65% and 85.72%-91.21%, respectively.…”

“…Concerning electrochemical precipitation of Mg(OH)2, the main goal of this investigation was to study the effect of concentration of salt solution, potential, and electrolysis time on the mass and elemental composition of the precipitate, which reflects the purity of MgO, produced from untreated and BaCl2-pretreated salt solution. We focused on the above electrochemical variables for their supposed significant roles in electrolysis [24,28]. The catalytic activity of the MgO produced was then tested in transesterification of coconut oil to produce biodiesel.…”

This study was conducted to explore the production of magnesium oxide from raw salt solution using electrochemical precipitation, followed by calcination. Electrochemical precipitation was conducted by electrolysis of the salt solution using nickel rods as cathodes and graphite as anodes. Two sets of salt solutions were prepared: one set without pretreatment and another with BaCl2 pretreatment. The solutions were used to study the effect of salt concentration, potential, and electrolysis time. The representatives of the MgO produced were tested as catalysts for transesterification of coconut oil. The results indicate that optimum mass of precipitate was produced from 400 mg/L salt solution electrolyzed using 8 V for 60 min. Elemental analysis using X-Ray Fluorescence (XRF) revealed the presence of Mg as the main component of the precipitate, confirming the electrochemical conversion of Mg2+ into solid Mg(OH)2. The MgO with the purity of 74.23% and 88.87% was produced from non-pretreated and pretreated salt solution, respectively. The transesterification experiments indicate that the yield of 90% and 98% was achieved using the MgO produced from non-pretreated and pretreated salt solution, respectively.

“…Several researchers have synthesized MgO nanoparticles using several methods, including sol-gel [7], sonochemical [8], co-precipitation [9,10], and chemical reduction [11]. Green synthesis techniques use reagents that are free of chemicals that are harmful to the environment such as using water solvents or plant extracts [12,13].…”

Nanoparticle fabrication using plant extracts is an important alternative method because it is non-toxic, biocompatible, and environmentally friendly. In this study, green synthesis of MgO nanoparticles using Moringa oleifera leaf water extracts was conducted by mixing the extract and a solution of magnesium chloride. The product was characterized using different techniques, i.e. UV-Visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The UV-Vis spectrum of MgO nanoparticles shows an absorption at 280 nm. The size of the synthesized MgO nanoparticles ranges from 20-50 nm. The antibacterial activity of MgO nanoparticles was seen from the zone of inhibition against Staphylococcus aureus (6.3 mm) and against Escherichia coli (6 mm). MgO nanoparticles have been successfully fabricated using Moringa oleifera leaf aqueous extracts, providing an alternative method for synthesizing MgO nanoparticles.
