Abstract
The methods like biogreen are advantageous over chemical and physical methods due to eco friendly and cost-effective synthesis of nanoparticles. Current study was designed for green synthesis of gold nanoparticles (GNPs) and their biological evaluation. Aqua extract of Muntingia calabura, Linn was used for the synthesis of GNPs and confirmed by UV visible and Fourier Transform Infra-Red (FTIR) spectroscopy. Further field emission Transmision electron microscope (TEM) and Particle Size Analyser was used for the shape zeta potential and size determination. In vitro Antioxidant, and tyrosinase inhibitor was determined by using standard protocols. The nanoparticles were spherical in shape and having average particle size of 88 nm. FTIR analysis revealed the possible involvement of phyto-constituents in gold nanoparticles of crude extract. Green synthesized nanoparticles showed the enhanced antioxidant properties and the tyrosinase inhibitor. Green synthesized GNPs showed enhanced biological activities. Present results also support the advantages of using biogreen method for the production of nanoparticles having the potential of antimicrobial and cytotoxic activities.
