The exigency to promulgate the rapid synthesis, non-hazardous, cost- effective and eco-friendly green method for the synthesis of nanoparticles utilizing the plants of great significance. This is a result for alternative method of high toxicity associated with the chemical procedure of synthesizing nanoparticles. The aim of the study was to monitor the potentiality of green synthesized AuNPs on microbial cell proliferation. Green method benign AuNPs were characterized by UV-visible Spectrophotometer, Dynamic Light Scattering (DLS), Zeta Potential and the size, shape and morphology of the AuNPs analysed with the Transmission Electron Microscopy (TEM). Maximum phytochemicals were found with the help of polar and the non- polar solvents in the selected stem bark of Wasura trifoliata. The synthesized AuNPs showed good antibacterial activity on selected two gram positive bacteria like Bacillus subtilis, Staphylococcus aureus and two gram negative bacteria like Escherichia coli, Klebsiella pneumoniae. The green synthesized AuNPs should helpful to develop new drug alternative to conventional in pharmaceuticals, pharmacognosy to diagnose various diseases.
