Abstract

Green synthesis approaches are acquiring importance due to their environmentally safe, commercial scalability, versatility, cost-effectiveness, simplicity and efficiency on large scale synthesis. The extract of Trachyspermum ammi was used for the synthesis of Al 2 O 3 nanoparticles. The green synthesized Al 2 O 3 nanoparticles were characterized by using by UV-Vis, FTIR, SEM, XRD and EDX. The green synthesized Al 2 O 3 nanoparticles were characterized by using by UV-Vis, FTIR, SEM, XRD and EDX. The absorbance at 345.4nm from UV-visible spectroscopy shows the formation of Al 2 O 3 nanoparticles. The FTIR results indicated the presence of functional groups responsible for the formation of nanoparticles and the peak between 710.71cm-1 and 871.92 cm-1 confirm the presence of Aluminium oxide. XRD analysis revealed the formation of Al 2 O 3 nanoparticles with average particle size 25.7nm calculated from Scherer formula. EDX analysis demonstrated the elemental composition. The phytochemical screening of Trachyspermum ammi was performed. The antibacterial activity of prepared Al 2 O 3 nanoparticles was investigated by Well diffusion method. Plant extract consist of numerous biochemical and phytochemical compounds that serve as capping and reducing agent that facilitates the production of non-toxic nanoparticles that are useful for pharmaceutical and biological applications.
