Abstract: Development of reliable and eco-friendly green processes for synthesis of metallic nanoparticles is an important step in the field of nanotechnology, since the other techniques have several disadvantages. In the present study, we used a novel approach to synthesize stable silver (Ag) NPs using<em> Macrotyloma uniflorum</em>,<em> </em>seed sprout powder and observed a rapid reduction of silver ions leading to the formation of stable silver nanoparticles in solution when exposed to sun light compared to other modes of synthesis. The UV-Vis spectrum of Ag NP in aqueous solution shows an absorbance peak around 450 nm due to Surface plasmon resonance. Silver nanoparticles were confirmed with FTIR analysis showed the presence of difference functional groups involved in capping the silver nanoparticles again, silver nanoparticles size was confirmed by SEM analysis which shows that particles were in the range of 30 to 50 nm in size. This study, to the best of our knowledge, is the first attempt to perform eco-friendly synthesis of Ag NPs using seed sprouts of <em>Macrotyloma uniflorum</em>,<em> </em>which may benefit various industries with wide range of applications.
