“…After that, the Adding tripolyphosphate (TPP) to the solution of the mixture of plant extract and chitosan at a ratio of 2.5:1 (% w/w) with continuous stirring and agitation at room temperature for 6 hours, reaching the equilibrium state represented by obtaining a viscous consistency with a distinctive color for the mixture, which represents the formation of nanoparticles and obtaining On the nanocomposite (methanolic extract of pumpkin peels with nano chitosan (Cu/Cs-NPs). The nanoparticles were separated from the liquid by centrifugation at 16,000 (revolutions/min) for an hour, the solution was filtered, and the precipitated portion was washed several times with deionized water, then dried and preserved until use [11]. Base solutions of the methanolic extract with nano chitosan (Cu/Cs-NPs nanocomposite) were prepared at two concentrations of 32 and 16 mg/mL, after which they were stored in dark amber glass bottles at 4°C until use.…”

“…The green synthesis of nano chitosan with the methanolic extract of pumpkin peels was characterized by °, 32.14°, 37.30°, 39.32°, 45.05°), on the other hand, Figure (11) shows the X-ray diffraction patterns of chitosan. The results showed that the 2θ value for chitosan at its main peak was 20.53° and an intensity level close to (1200 cont.…”

The current study aimed to prepare a nano-extract from pumpkin peels and study its antioxidant effectiveness. The methanolic extract of pumpkin peels loaded with nanoparticles was prepared using the ionic gel method, and was characterized using techniques represented by an ultraviolet (UV) spectrophotometer and a scanning electron microscope (SEM), in addition to To X-ray scattering (XRD) and infrared spectroscopy (FTIR) techniques. The results of the diagnosis of nanoparticles by scanning electron microscope (SEM) showed that the nanoparticles are spherical in shape and are of a nanometer size. The size of the particles of the Cu/Cs-NPs nanocomposite ranges in diameter from (53.04-78.05) nanometers and has a relatively homogeneous morphology. Five of the compounds were also identified. Phenolics (Galic acid, Apigenin, kaempferol, Quercetin, Rutin) by matching them with the detention time of standard compounds. The methanolic extract of pumpkin peels gave the highest value of total phenolic content, reaching 84.16 mg/g at a concentration of 50 mg/ml, while the content of total phenols in the Cu/Cs-NPs nanocomposite decreased, compared to the methanolic extract, where the highest value of total phenolics reached 12.21. mg/g at a concentration of 30 mg/ml. In addition, the results of the antioxidant activity in removing free radicals showed that the Cu/Cs-NPs nanocomposite was excelled by average of 59.34% at a concentration of 3 mg/ml over the methanolic extract by average of 92.68% at a concentration of 50 mg/ml.
