Tyrosinase inhibitory activity of silver nanoparticles treated with Hovenia dulcis fruit extract: An in vitro study

Abstract This work describes a novel approach for the preparation of silver nanoparticles (AgNPs) using Hovenia dulcis fruit bodies, as opposed to physical and chemical methods. The active phytochemicals present in the extract reduced silver ions (Ag + ) to AgNPs (Ag 0 ). The results of UV–vis spectrum, transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS) revealed that the synthesized AgNPs were in the size range of 40–50 nm. In addition, the synthesized AgNPs were evaluated for their tyrosinase inhibitory activity using L-DOPA as the substrate with significant results.
