“Plant-mediated green synthesis of Ag nanoparticles using Rauvolfia tetraphylla (L.) flower extracts: Characterization, Biological activities and screening of their catalytic activity in formylation reaction”

Abstract

Various plant extracts have currently been used in the bioproduction of nanoparticles with enormous applications. In this study, Rauvol a tetraphylla ower extracts were employed to obtain silver nanoparticles (Ag NPs) in bioproduction. The biologically produced nanoparticles were characterized by XRD, FTIR, UV-Vis, BET, SEM, EDXA, and TEM analyses. Phytochemical screening of the Rauvol a tetraphylla ower extracts indicated presence of 9 di erent constituents. Bioreduction of Ag NPs by phytochemicals was revealed by FTIR analysis. The elemental composition of Ag NPs was reported by spectral EDXA. The Ag NPs exhibited anti-bacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella aerogenes, and Escherichia coli; anti-fungal activity against Penicillium citrinum and Aspergillus avus; and antimitotic activity. The response of amines in formic acid in the presence of an Ag NPs catalyst in dissolvable free condition provided high yielded convention for the N-formylation to shape the comparing formamide derivatives. N-fromylation had the characteristics of incite recyclability, clean strategy, environmental friendliness under milder response conditions, and straightforward work-up with brilliant yield of the coveted items.

Overview on Methods of Synthesis of Nanoparticles

“…Nanoparticles synthesis using algae takes a shorter duration than other biosynthesizing methods. To synthesize AgNPs of varying sizes and shapes certain seaweeds (Sargassumwightii and Fucusvesiculosus) can be used [37,38].…”

Green Synthesis of Ag Nanoparticles by Methadone and their Cytotoxicity against Human Breast Cancer Cells

“…Green synthesis is a good alternative for conventional physical and chemical preparation techniques, which has advantages such as biocompatibility and low production cost. Algae, fungi, plants, and bacteria extensively employed for the preparation of nanoparticles by green synthesis [6][7][8]. Among metallic nanoparticles, silver nanoparticles (AgNPs) are one of the most important materials that extensively used in various pharmaceutical and healthcare industries.…”
