Phytochemical and Spectral Studies of Synthesis sulfur Nanoparticles using Sophora japonica Pods Extract

Abstract

This study aims to investigate the aqueous extract of Sophora japonica pods for the presence of various phytochemicals and to synthesize sulfur nanoparticles. The presence of various phytochemicals viz. polyphenols, alkaloids, terpenoids, flavonoids, and tannins were investigated by standard biochemical methods. A rapid, green and novel approach for synthesis sulfur nanoparticles (SNPs) from sodium thiosulfate in the presence of Sophora japonica pods aqueous extract in one-pot reaction at ambient temperature. The resulting sulfur nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that sulfur nanoparticles were successfully synthesized in sphere shape, and with an average particle size 5-100 nm. The effect of plant pods extract concentration on particle size of sulfur nanoparticles shows that can significantly reduce the particle size without changing the shape. The results revealed that the aqueous extract of Sophora japonica pods act as capping, dispersing and stabilizing agent for sulfur nanoparticles. This method is a novel approach for production nanosized sulfur particles, which could be applied to prepare sulfur nanoparticles for application in antimicrobial activity, fertilizers, and plant protection.

Green synthesis of zinc oxide nanoparticles usingCocos nuciferaleaf extract: characterization, antimicrobial, antioxidant and photocatalytic activity

“…Several types of metal and metal oxide NPs such as aluminium, nickel, silver, copper, copper oxide, iron, iron oxide, cerium dioxide, titanium dioxide and zinc oxide (ZnO) are commonly known [1,2]. The NPs can be prepared by several physical, chemical and biological methods, but physical and chemical methods are associated with high energy demand, and sometimes generating poisoned and perilous chemicals, which may lead to related dangers [3,4]. To minimize these problems, a safe, costeffective and less hazardous synthesis procedure has already been developed by modern scientists, namely the biological or green method using plant extract with a low concentration of the chemicals.…”
