“…These results might arise from the interference of several functional groups existing in the Ib1 and Ib2 extracts, which might have played a vital part in the capping and stabilization procedure during Ib1-AgNPs and Ib2-AgNPs synthesis. 22,72,80 The Ib1-AgNPs and Ib2-AgNPs showed higher scavenging effect against DPPH-free radicals in comparison to ABTS radical cations, as evident from less IC 50 values (Table 1), which is consistent with previous reports. 22,72,81 However, Ib2-AgNPs demonstrated slightly more potent antioxidant potential than the Ib1-AgNPs in entire four assays (Table 1), which may be related with the combination of additional oxidants on the external surface area of Ib2-AgNPs.…”

“…The current result is similar with a previously reported result. 10,22,72 The cytotoxicity potential of Ib1-AgNPs and Ib2-AgNPs can be credited to the initiation of intracellular oxidative stress. 22,26 According to the earlier studies, the cytotoxicity activity of Ib1-AgNPs and Ib2-AgNPs might be the end result of oxidative stress induced in the cells rather than the toxic effect of Ag + ions.…”

Background: Ipomoea batatas (L.) Lam.(Ib) has high content of various beneficial nutrients which helps in improving and maintaining human health. It is well known as a functional food and also a valuable source of unique natural products. It contains various phenolic and flavonoid bioactive compounds. Methods: In this study, using the outer peel of two varieties of Ib : Korean red skin sweet potato and Korean pumpkin sweet potato, silver nanoparticles (AgNPs) were synthesized (termed Ib1-AgNps and Ib2-AgNps), respectively. Characterization of Ib1-AgNPs and Ib2-AgNPs was carried out through scanning electron microscopy, Fourier-transform infrared (FT-IR) spectroscopy, energy-dispersive X-ray analysis, X-ray powder diffraction and UV-Vis spectroscopy. Further, the bio-potential of the synthesized AgNPs was investigated by antidiabetic (α-glucosidase assay), antioxidant (free radical scavenging assays), antibacterial (disc diffusion method) and cytotoxicity assays (cell viability against HepG2 cells). Results: FT-IR spectroscopy revealed the contribution of bioactive compounds existing in Ib1 and Ib2 extracts, in the biosynthesis and equilibrium of the AgNPs. Although the Ib2-AgNPs had a higher atomic percentage of Ag in comparison with Ib1-AgNPs, in the antidiabetic assay, the inhibition percentage of α-glucosidase was higher for AgNPs of Ib1 than Ib2, at all three concentrations examined. From the cytotoxicity results, HepG2 cancer cells were more sensitive to the Ib1-AgNPs in comparison to the Ib2-AgNPs-treated HepG2 cells. The antioxidant prospective was higher in Ib2-AgNPs than Ib1-AgNPs. Moreover, the Ib2-AgNPs showed inhibitory action against all five tested pathogenic bacteria, producing an inhibition zone of 8.74-11.52 mm while Ib1-AgNPs had an inhibitory effect on four of them, with an 8.67-11.23 (mm) inhibition zone. Conclusions: Overall, the results concluded that the Ib2-AgNPs exhibited relatively higher functional activity than Ib1-AgNPs, which might be credited to the greater abundance of bioactive compounds existing in Ib2 extract that acted as reducing as well as capping agents in the synthesis of Ib2-AgNPs. Overall, the current study highlights a novel cost-effective and eco-friendly AgNPs synthesis using food waste peels with biocompatibility and could be potentially utilized in biomedical and pharmaceutical industries.

A facile, efficient, and environmentally friendly protocol for the solvent‐free synthesis of antipyrine‐ linked quinoline derivatives catalyzed by CeO2–TiO2 nanocatalyst under ultrasonication is developed. Antipyrine derivatives are involved in various synthetic processes and exhibit valuable biological activities, such as antibacterial, anti‐inflammatory, antioxidant, and anticancer properties. Biowaste‐ derived CeO2–TiO2 nanoparticles have been synthesized using outer covering calyx leaves extract of Physalis peruviana fruits and utilized for the construction of biologically important antipyrine derivatives by the multicomponent reaction in short reaction time with excellent yield. The nanocatalyst was characterized by FT‐IR, powder X‐ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electron dispersion spectroscopy (EDS). The functionalized nanoparticles show excellent reusability without any significant loss in catalytic activity. The hot filtering experiment shows that there is no noticeable leaching or boomerang effect and that the catalysis is heterogeneous in nature. All synthesized compounds underwent screening for antibacterial activity against selected microorganisms, and their antioxidant activity was assessed using DPPH (2,2‐diphenyl‐1‐picrylhydrazyl). Some of the synthesized compounds exhibited promising results in both screenings.
