Objective: The design like bio-nano particles are beneficial over chemical and physical composition due to the eco-friendly and lower-cost synthesis
of nanoparticles. The current study was purposed for the biosynthesis of gold nanoparticles (GNPs) and their antioxidant evaluation.
Methods: Aqua extract of Muntingia calabura, Linn was applied for the synthesis of GNPs and confirmed by UV visible and ATR-Fourier Transform
Infra-Red (ATR-FTIR) spectroscopy. Transmission Electron Microscope and Particle Size Analyser were used for the shape zeta potential and
determination of size. Antioxidant activity was examined by DPPH (1,1 diphenyl-2-picryl-hydrazyl) radical scavenging method.
Results: The result showed that UV–vis absorption spectra of H Au Cl4
Conclusion: Green synthesized GNPs showed enhanced biological activities. Present results also support the benefit of using the biosynthesis
method for the production of gold nanoparticles that have the potential of antioxidant and biology activ
