Rapid, eco‐friendly, and cost‐effective one‐pot synthesis of copper nanoparticles is reported here using medicinal plants like Gnidia glauca and Plumbago zeylanica. Aqueous extracts of flower, leaf, and stem of G. glauca and leaves of P. zeylanica were prepared which could effectively reduce Cu²⁺ ions to CuNPs within 5 h at 100°C which were further characterized using UV‐visible spectroscopy, field emission scanning electron microscopy, high‐resolution transmission electron microscopy, energy dispersive spectroscopy, dynamic light scattering, X‐ray diffraction, and Fourier‐transform infrared spectroscopy. Further, the CuNPs were checked for antidiabetic activity using porcine pancreatic α‐amylase and α‐glucosidase inhibition followed by evaluation of mechanism using circular dichroism spectroscopy. CuNPs were found to be predominantly spherical in nature with a diameter ranging from 1 to 5 nm. The …
