“…These peaks can be attributed to the vibrations of O-H, C-H, C=C stretching, and C-O stretching, respectively. Notably, the substantial absorption peaks observed at 1029 cm −1 , 2922 cm −1 , and 3414 cm −1 primarily correspond to the polyphenols extracted from the plants [ 28 ]. Additionally, peaks at 3795 cm −1 , 3452 cm −1 , 3439 cm −1 , 3430 cm −1 ,3422 cm −1 , 3418 cm −1 , 3360 cm −1 , and 3255 cm −1 can be ascribed to the stretching vibrations of the O-H or N-H groups present in alcohol or phenol compounds that bind to the surface of AgNPs [ 44 , 45 , 46 , 47 , 48 ].…”

“…Moreover, peaks at 2930 cm −1 , 2923 cm −1 , 2922 cm −1 ,2921 cm −1 , 2900 cm −1 , and 2880 cm −1 are associated with the C-H stretching vibrations of alkanes [ 23 , 28 , 35 , 46 , 47 ]. The presence of aldehyde or ketone functional groups (C=O) from flavonoid and tannin derivatives can be inferred from the peaks at 1617 cm −1 ,1626 cm −1 , 1650 cm −1 , and 1653 cm −1 [ 44 , 47 , 49 ].…”

“…Plant-based synthesis of silver nanoparticles has been achieved using a variety of plant materials, including rice leaves, wheat leaves, the leaves of Pongamia glabra, petals of C. oblonga , Citrus limetta peel, Cleome viscosa , and other plants [ 18 , 23 , 24 , 25 , 26 , 27 ]. Plant extracts abundant in phytoconstituents, such as alkaloids, flavonoids, and terpenoids, have the ability to reduce metal salts from Ag + to Ag 0 , leading to the synthesis of AgNPs [ 28 ]. Due to the presence of diverse biomolecules in different plants, nanoparticles generated from distinct plant sources may demonstrate varying antimicrobial properties.…”

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.

“…The broad and shallow absorption at 3400 cm À 1 region in the ethanolic extract C. alata leaf spectra indicates the presence of the hydroxyl (OH) group from polyphenolic compounds such as flavonoids. [34] Absorption at 2943 and 2887 cm À 1 represents the stretching vibration of aliphatic CÀ H which means that ethanolic extract of C alata leaf contains glycoside compounds. [35] The peak at 1638 cm À 1 corresponds to C=O stretching and NÀ H bending primary amides.…”

Diabetes mellitus, a widespread chronic illness categorized by elevated blood sugar levels, poses a significant health burden. This study aimed to synthesize an optimal oleogel formula and investigate its impact on accelerating diabetic wound healing through a multidimensional approach. The evaluation spanned in vitro examination utilizing bacterial cultures, and in vivo assessments on mice, involving a meticulous 9‐day observation of wound healing percentages. The successful synthesis and characterization of AgNPs and Na‐CMC laid the foundation for further exploration. Oleogel formulation optimization using Response Surface Methodology (RSM) revealed the most effective composition featuring Na‐CMC at 4.5 %, beeswax at 12.5 %, and a stirring temperature of 80 °C. Manufacturing success was affirmed through comprehensive testing encompassing pH, organoleptic properties, dispersion, gelation time, and FTIR analyses. Characteristics of extracted nanoparticles were scrutinized through SEM‐EDX, PSA, and Zetapotential tests. In vitro evaluations showcased the commendable antibacterial activity of AgNPs. Notably, in vivo observations highlighted the superior wound healing capabilities of oleogel ointment enriched with AgNPs. These findings collectively underscore the promising potential of the synthesized oleogel in promoting the healing process for diabetic wounds, validated through diverse analytical approaches, marking a significant stride toward effective therapeutic interventions in diabetes‐related wound management.
