In the present investigation, iron oxide nanoparticles were synthesized using a simple, rapid and green method using Actinodaphne madraspatna Bedd leaves as reducing agent. The UV-visible spectra showed strong absorption band in the visible region, which confirms the formation of iron oxide nanoparticles. TEM images showed distinct spherical shaped particles with average size of 20 nm. FT-IR spectra depicted the presence of phytomoities in Actinodaphne madraspatna Bedd leaves which may probably act as a reducing and capping layer and thus facilitating the formation of nanoparticles.
