Abstract :
The green synthesis of silver nanoparticles (AgNPs) using Bombax cebia leaf extract was successfully
carried out, as the change in the color of the solution from blue color to dark brown color exhibits the reduction of
the silver in aqueous solution. The exact mechanism for the formation of nanoparticles in living plants is not
yet known, nor investigated in depth. The process, conceptually, appears to be close to the mechanisms of bio
mineralization due to excitation of surface plasmon vibrations in silver nanoparticles. The pH of the solution during
this reaction was in acedic range, which implies that the reaction occurs under acidic condition. It is to be observed
that silver nanoparticles exhibit yellowish brown color in aqueous solution. bombaxycebia belongs to family plante
and having medicinal importance. The aqueous extract of leaves of bombaxycebia was used for the synthesis of silver
nanoparticles.
