    The synthesis of nanoparticles from plant sources has proved to be an effective and alternate method for the novel production of nanoparticles. A number of synthesis techniques have been developed including the chemical reduction of silver ions in aqueous solutions, with or without stabilizing agents, thermal decomposition in inorganic solvent, and chemical and photo reduction. Our study deals with the synthesis of silver nanoparticles from Cardiospermum helicacabum leaf extracts mostly fresh. The samples consisted of the leaf extracts at two different temperatures 65°C (5min,10min,15 min) and 95°C for 5 min. The plant extract at 95°C, however showed better and accurate nanoparticles formation with AgNO3 with time. Thus showing that the extraction temperature plays an important role in formation of nanoparticles. Also U.V Spectrophotometer studies show a graph that shows gradual increase of nanoparticles concentration with time, temperature, and sample characteristics. From these results we can conclude that Cardiospermum helicacabum is a potential source for nanoparticles synthesis and have identified an optimum temperature for its efficient synthesis. Depending Upon the particle size application of the nanoparticles varies. Particle size, shape can be determined by characterization procedure SEM and XRD .Synthesizing Silver
    nanoparticles by medicinal plants is echo friendly and good antimicrobial efficiency against bacteria, viruses and other microorganisms. Now days widely applicable in medicinal fields for Cancer treatments, AIDS, Epilepsy etc.
