Abstract :
In this present study, an environmentally friendly and rapid method for the
synthesis of silver nanoparticles (SNPs) has been reported using Ziziphus
Vulgaris (ZV) unripe fruit extract under mild conditions. The synthesized
silver nanoparticles have been characterized by transmission electron
microscopy (TEM), X-ray diffraction (XRD), fourier transform infrared
spectroscopy (FT-IR) and ultraviolet-visible spectroscopy (UV–vis).
Transmission electron microscopy analysis confirmed that the synthesized
SNPs have spherical shape and their average size is about 20 nm. Moreover,
antioxidant activity, total phenolic and flavonoid content of unripe fruit
and seed were analyzed by DPPH free radical-scavenging, Folin Ciocalteu
and aluminum chloride (AlCl3) assays, respectively. Different extracts of
unripe fruit showed higher antioxidant activity, total phenol and flavonoid
than seed of Ziziphus vulgaris.
