Description:
<jats:title>Abstract</jats:title><jats:p>In the present study, aqueous leaf extract of <jats:italic>Strobilanthes cordifolia</jats:italic> J.R.I.Wood was combined with silver nitrate to synthesis silver nanoparticles (AgNPs). The AgNPs were characterized using visible spectroscopy (UV), X‐ray diffraction (XRD), Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), energy dispersive X‐ray (EDaX), particle size analysis, and transmission electron microscope (TEM). The UV spectrum absorption peak occurred at 438 nm. The FTIR analysis of the AgNPs indicated the presence of functional groups such as aldehyde, alkenes, and carboxylic acids. The crystalline structure of AgNPs was confirmed by XRD. The AgNPs have a spherical shape according to SEM. The AgNPs components composition was confirmed by EDaX. The particle size distribution of AgNPs is monodispersion in the range at 42.54 nm. TEM demonstrated the AgNPs size to be between 11.35 and 34.90 nm. The AgNPs exhibited good antibacterial property against <jats:italic>Escherichia coli</jats:italic> and <jats:italic>Staphylococcus aureus</jats:italic>. The antioxidant activity of the AgNPs was represented by increased DPPH, ABTS, and H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> activities.The antidiabetic activity of the AgNPs was indicated by the inhibition of α‐amylase and α‐glycosidase and anti‐inflammatory highest albumin denaturation and HRBC membrane stabilization properties. Further, the AgNPs also significantly inhibited the MCF‐7 cell lines. These results clearly suggest that the synthesized AgNPs using <jats:italic>S. cordifolia</jats:italic> leaves could have several potential biomedical applications.</jats:p>
