Green synthesis of gold nanoparticles using different medicinal plants and its uv-vis spectroscopic analysis and antibacterial activity

Background: Gold nanoparticles are the most prominent metal nanoparticles and having wide range of applications in drug delivery and many therapeutic potentials. Materials and Methods: In this present investigation we have used some Indian herbal plants for the green synthesis of gold nanoparticles and its antibacterial efficacy was measured. Results: The medicinal plants such as Alternanthera bettzickiana, Gymnema sylvestre and Andrographis paniculata used for the synthesis and characterized using UV-vis spectroscopy. The antibacterial activity of gold nanoparticles such as Bacillus subtilis, Staphylococcus aureus, Micrococcus luteus, Enterobacter aerogenes, Salmonella typhi and Pseudomonas aeruginosa. Conclusion: The plant mediated gold nanoparticles may used in the controlling of pathogens in various medical field.
