Antibacterial Activity of Silver nanoparticles and Pomegranate (Punica granatum L.) Extracts

Green synthesis of silver nanoparticles using Omani pomegranate peel extract and two polyphenolic natural products: characterization and comparison of their antioxidant, antibacterial, and cytotoxic activities

“…Appearance of new broad surface plasmon resonance peaks at 425 nm, 421 nm, and 413 nm in the UV-Vis absorption spectra (Fig. 2) for Q-AgNP, P-AgNP, and GA-AgNP, respectively are consistent with the literature data [11,24]. Four intense peaks in the XRD spectra (2θ = 37.84-38.62°, 44.16-44.62°, 64.16-64.96°, and 82.06-82.42°) for all the three samples showed a pattern that matched with the reference cubic silver crystal further confirming formation of AgNPs (Fig.…”

“…In green synthesis of AgNPs, the plant extract has a dual action of being both the reducing agent and the capping agent. Pomegranate peel extracts (PPE) elsewhere have been used for the synthesis of AgNPs and were shown to exhibit good antimicrobial activity [22][23][24]; however, literature review indicated that AgNPs prepared using Omani PPE have not yet been explored for their antioxidant and cytotoxicity activities.…”

Efficient Bioelectrochemical Cell Generation and Green Synthesis of Silver Nanoparticles Using Pomegranate and Pineapple Peel Extracts: A Comprehensive Characterization Study

“…To underscore the environmentally friendly attributes of the AgNPs, their UV absorption spectrum within the 200-600 nm range was meticulously recorded and compared with the UV spectrum of PgP and PnP. Te UV-Vis absorption spectra revealed the emergence of distinctive broad surface plasmon resonance peaks at 393 nm and 397 nm for PgP AgNPs and PnP AgNPs, respectively, by established literature data [27][28][29]. Te UV-Vis absorption spectra revealed the emergence of distinctive broad surface plasmon resonance peaks at 291 nm and 297 nm for PgP and PnP extracts, respectively.…”
