ObjectiveTo synthesize the silver nanoparticles (AgNPs) by reduction of silver ions into nano silver, using ripened berry extract of Lantana camara and evaluate its antioxidant activity against 1, 1-diphenyl-2- picrylhydrazyl.MethodsThe prepared AgNPs were characterized by visual, UV-visible spectrophotometer, dynamic light scattering and transmission electron microscopy with selected area electron diffraction.ResultsTransmission electron microscopy and dynamic light scattering analysis confirmed the AgNPs are spherical and 75.2 nm average sized. Selected area electron diffraction analysis supports that the obtained nanoparticles were in crystalline form. In addition, the antioxidant efficacy of prepared AgNPs was found to be higher than berry extract against 1, 1-diphenyl-2- picrylhydrazyl.ConclusionsFrom the results obtained it is suggested that surface modified AgNPs at lower concentration, showed higher antioxidant activity than berry extract against 1, 1-diphenyl-2- picrylhydrazyl and could be used effectively in future ethno pharmacological concerns
