<br/><br/> Here we report a novel biological approach for the formation of zinc nanoparticles using Guazuma ulmifolia (Lam) leaves. Zinc acetate was reduced with aqueous solution of Guazuma ulmifolia leave extracts. X-Ray diffraction (XRD) pattern reveals the formation of zinc nanoparticles, which shows crystallinity. Scanning electron microscopy (SEM) suggested particles size in the range of 46-96nm and spherical shape. UV absorption studies of zinc nano particles showed absorbance at 698nm and FT-IR studies of zinc nanoparticles confirmed the presence of bio active phyto-constituents in the formed nano particles. The DPPH free radical inhibition study confirmed that the synthesized zinc nano particles have potential radical inhibiting activity.
