Green Synthesis of Silver Nanoparticles from Nyctanthes arbor tristis L. Leaf Extract and Evaluation of Its Antidiabetic and Antioxidant Properties

In Nycanthes arbor-tristis, green production of silver nanoparticles has been described. After combining 1% aqueous leaf extract with 1 mM silver nitrate solution and letting it sit for 10 minutes at room temperature in the light, nanoparticles were effectively created. The brown reaction mixture's UV–Vis spectra revealed a strong surface plasmon resonance at 460 nm. It verified that silver nanoparticles are biosynthesised. SEM and TEM were used to characterize the nanoparticles. According to the data, produced nanoparticles have a diameter between 10 and 50 nm. The polycrystalline nature of the biosynthesized nanoparticles was verified by XRD measurements. Compared to extract, silver nanoparticles demonstrated a stronger antidiabetic effect. Every clinical isolate with antidiabetic properties was sensitive to nanoparticles. Additionally, the silver nanoparticles showed strong free radical scavenging capabilities.
