Green Synthesis of Silver Nanoparticles Using Pomegranate Peel Extract

Abstract

Silver nanoparticle (AgNP) is extensively used in the consumer products and in the medical applications due to its antibacterial property. In this study, AgNPs were synthesized by a simple green chemistry procedure using three difference pH values of pomegranate peel extract as reducing and stabilizing agent and silver nitrate (AgNO3) as a precursor. The formation of AgNPs was elucidated using various instrumentation techniques including UV-Vis, FTIR, XRD, EDX and TEM. UV-Vis spectra showed the surface plasmon resonance (SPR) peak in the range of 400-500 nm. Crytalline nature and fcc phase of AgNPs were revealed by XRD pattern. FTIR analysis provided the presence of phytochemicals responsible for the reduction and stabilization of AgNPs. TEM analysis demonstrated that size and morphology of the prepared AgNPs were in the nanoscale range of 5-45 nm with irregular spherical in shape. The existence of the elemental silver was observed from EDX analysis. Furthermore, AgNPs showed an effective antibacterial activity to Staphylococcus aureus and Escherichia coli.

Cytotoxicity and antibacterial activities of plant-mediated synthesized zinc oxide (ZnO) nanoparticles using Punica granatum (pomegranate) fruit peels extract

“…As previously reported, some major phenolic compounds identified in pomegranate peel include punicalagin, gallic acid, ellagic acid, chlorogenic acid, caffeic acid, punicalin, apigenin, quercetin, pelargonidin, cyanidin, granatin A and granatin B [31]. These compounds are primarily concentrated in the peel portion of P. granatum and have been proven to aid in green synthesis of a wide range of different NPs [16,32,33].…”

Green Synthesis and Characterization of Alchemilla Vulgaris Silver Nanoparticles

“…The same type of SEM analysis is done during the green synthesis of Ag NPs from pomegranate peel extract. Upon SEM analysis the particle size obtained for the synthesized Ag NPs were in the range of 40-80nm [29]. So the nanoparticle which comes in the range of 0-100nm is considered to be the silver nanoparticle.…”

Fabrication of biogenic silver nanoparticles from Ficus religiosa bark extract and their application for chromium removal

“…The sample was exposed to a UV-vis spectrophotometer at a bandwidth of 1.5 nm, adjusting the wavelength range from 300 to 700 nm using a xenon lamp at a graph height of 2.00 A. F. religiosa aqueous bark extract showed absorbance peak at 283 nm whereas the synthesized AgNPs showed absorbance peak at 448 nm as shown in Figure 1. AgNP spectra between 400 and 500 nm were also reported using Coccinia grandis and Phyllanthus emblica, Garanium leaf extract, pomegranate peel extract and Henna plant aqueous extract (Kumar et al, 2012;Nayagam et al, 2018;Phongtongpasuk & Poadang, 2015;Shankar et al, 2003).…”
