In this paper, a green synthetic route was developed to synthesize tungsten, tin and lead nanoparticles mediated by the Cucurbita maxima flower extract, Cucurbita is monoecious (unisexual flowers, with male and female on the same plant), bearing solitary actinomorphic flowers (10-20 cm across) that are open for a single day Cucurbita maxima was a traditional vegetable food for south Indian. The flower of Cucurbita maxima aqueous extract is analyzed for the phytochemical constituent. The synthesized nanoparticles are characterized by UV, FTIR, XRD and SEM with EDS. The synthesized three nanoparticles also screened by gram positive and negative bacterial strains.
