Green synthesis of nanoparticles using plant source has been given much importance. In the present
study, silver nanoparticles (AgNPs) were synthesized using the ethyl acetate and methanol (EA: M
40:60) extracts of the inflorescence of the tree Cocous nucifera. The synthesized nanoparticles were characterized
by UV–visible spectroscope, FTIR and TEM analysis. The particle size of the synthesized AgNPs
was 22 nm as confirmed by TEM. The qualitative assessment of reducing potential of the extracts of
inflorescence indicated the presence of reducing agents. Synthesized AgNPs exhibited significant
antimicrobial activity against human bacterial pathogens viz., Klebsiella pneumoniae, Bacillus subtilis,
Pseudomonas aeruginosa and Salmonella paratyphi.
