Currently the development of plant-mediated biogenic nanoparticles is gaining much attention. It is notable that the biogenic nanoparticles particularly silver nanoparticles are therapeutically more effective than its chemically synthesized form. Thus, here in, the development of silver nanoparticles (Fj-AgNPs) using aqueous extract of ripe fruit of Flacourtia jangomas as a reducing agent is investigated. The developed Fj-AgNPs were additionally compared with ammine modified silver nanoparticles (Am-AgNPs), developed through chemical route using the reported approach and confirm the phyto-reduction of Ag + to Ag 0 .UV–visible spectrum has exhibited a peak at 418 nm and FTIR peak profile (at 1587.6, 1386.4, and 1076 cm −1 with corresponding compounds) in addition to the diffraction peak at 38°, 44°, 64°,78° in PXRD spectrum confirmed the synthesis of Fj-AgNPs with 8.29 nm average crystallite size. Enhanced anti-bacterial effect is observed in the case of Fj-AgNPs as compared to Am-AgNps. These results refer to the idea that the use of the aqueous extract of ripe fruit of Flacourtia jangomas could be a good replacement of EDTA in the synthesis of silver nanoparticles. Graphic abstract
