“…A significant antioxidant power has been established for the fruits and the possible mechanisms of action related to the regulation of certain signaling pathways have been indicated. Recent studies have reported an increase in the antioxidant potential of the species with the application of nanotechnology, almost equal to that of ascorbic acid [ 37 ].…”

Invasive species as sources of natural components are of increasing interest for scientific research. This is the case of Ailanthus altissima, which belongs to the top 100 of the most dangerous invasive plant species in Europe, and which is the subject of the present study. The purpose of the research was to analyze the main phenolic compounds in the flowers, leaves, and stem bark of A. altissima and determine the DNA-protective and antioxidant potential of their ethanolic extracts. HPLC profiling revealed the presence of 6 flavonoids and 10 phenolic acids, of which 15 were found in flowers, 14 in leaves, and 11 in the stem bark. Rutin (5.68 mg/g dw in flowers), hesperidin (2.67 mg/g dw in leaves) and (+)-catechin (2.15 mg/g dw in stem bark) were the best-represented flavonoids. Rosmarinic (10.32 mg/g dw in leaves) and salicylic (6.19 mg/g dw in leaves) acids were predominant among phenolic acids. All plant extracts tested showed in vitro antioxidant activity (determined by DPPH, ABTS, FRAP, and CUPRAC assays) and DNA-protection capacity (assay with supercoiled plasmid DNA—pUC19). The highest antioxidant activity was recorded in the flower parts (in the range from 661 to 893 mmol TE/g dw), followed by the leaves. A DNA protective potential for A. altissima leaf and flower extracts has not been established to date. In addition, the main microscopic diagnostic features of studied plant substances were described, with data for the flower parts being reported for the first time. The present study proves that A. altissima could be a natural source of DNA protection and antioxidants.

“…Different stretching modes are represented by different bands. According to Figure 5 A,B, the hydroxyl alcohol group’s (O-H) fundamental mode of vibration is at 3442 and 3434.24 cm −1 , symmetric alkenes (C≡C) are at 2114 and 2276.74 cm −1 , (C-C) aromatic stretching is at 1796 and 1730.91 cm −1 , and (C-N) amine C-N stretching is at 1364 and 1369.63 cm −1 , for ZnO-NRNs and the extract, respectively [ 45 ]. The presence of the alkene group was identified at the wavenumber of 1796 cm −1 .…”

This study successfully synthesized zinc oxide nanorod needles (ZnO-NRNs) using an environmentally friendly method employing Cymbopogon Proximus extract. The resulting ZnO-NRNs exhibited exceptional physicochemical and structural properties, confirmed through various characterization techniques, including UV-Vis spectrophotometry, dynamic light scattering (DLS), transmission electron microscopy (TEM), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX). The analysis revealed a hexagonal wurtzite structure with high crystallinity, a 3.6 eV band gap, and a notably blue-shifted absorption band. ZnO-NRNs showed impressive photocatalytic activity, degrading Rhodamine B dye by 97% under UV and visible sunlight, highlighting their photostability and reusability. This green synthesis process offers cost effectiveness and environmental sustainability for practical applications.

“…Inorganic materials, particularly metal nanoparticles (NPs), have been found to possess antibacterial properties and exhibit greater stability under harsh conditions and high temperatures compared to organic materials [ 17 ]. AgNPs are one of the most commonly used nanomaterials because of their antimicrobial properties against a variety of pathogenic bacteria, and silver ions released from AgNPs are thought to play a crucial role in antibacterial activity [ 18 , 19 ].…”

“…Due to the presence of diverse biomolecules in different plants, nanoparticles generated from distinct plant sources may demonstrate varying antimicrobial properties. Hence, it is imperative to explore new plant extract sources for nanoparticle synthesis to enhance the antimicrobial efficacy of the nanoparticles [ 17 ]. Jasminum nudiflorum Lindl, commonly cultivated as an ornamental plant and used in traditional medicine in China, is distinguished by the presence of dicyclic iridoid glycosides, pigments, flavonoids, and fatty acids in its flowers [ 29 ].…”

The synthesis of metal nanomaterials is a timely topic due to their widespread use in fields such as crop protection, the environment, medicine, and engineering. Green synthesis of nanoparticles, which uses plant extracts instead of industrial chemical agents to reduce metal ions, has been developed to decrease costs, reduce pollution, and improve environmental and human health safety. In this paper, silver nanoparticles (AgNPs) were synthesized from the flower extract of Jasminum nudiflorum. The green synthesized AgNPs were characterized by UV-Vis, FTIR, XRD, SEM, and other technologies. The antifungal activity of the prepared AgNPs against Alternaria longipes was tested using the plate method, the concentration dilution method, and other methods, and the antioxidant activity of the prepared AgNPs was evaluated by DPPH and hydroxyl free scavenging methods. The results showed that AgNPs synthesized from J. nudiflorum flower extract have a face-centered cubic structure (fcc), and the average grain size of the nanoparticles is 13 nm; they are also mainly spherical in shape. Additionally, the concentration of AgNPs (ranging from 16 to 128 μg/mL) significantly inhibited the mycelial growth of A. longipes in comparison to the control. The inhibitory rate gradually increased with increasing AgNP concentration, ranging from 70.64% to 79.60% at a concentration of 128 μg/mL. The minimum inhibitory concentration was observed at 32 μg/mL. AgNPs induced overaccumulation of MDA in A. longipes, resulting in cell membrane damage and nucleic acid leakage. Moreover, the AgNPs have significant antioxidant properties, which increase with increasing concentration. The clearance rate of DPPH was 25.46 ± 0.90% when the concentration of AgNPs was 8 μg/mL, and the clearance rate of the hydroxyl radical was 28.62 ± 0.59% when the concentration of AgNPs was 128 μg/mL. Thus, the flower extract from J. nudiflorum holds potential as an environmentally friendly and green alternative for the synthesis of AgNPs, which have antifungal and antioxidant potential.
