Abstract

Since ancient times, Asparagus racemosus, a traditional herb with various health advantages, has been used to cure a wide range of illnesses. Researchers sparked a lot of interest in the biological methods for producing nanoparticles (NPs). This study’s objective was to synthesize titanium dioxide nanoparticles (TiO2 NPs) utilizing the top-down nanofabrication method. Asparagus racemosus root extract was used to produce titanium nanoparticles utilizing green chemistry. The nanoparticles were characterized using UV-Visible spectroscopy, SEM (Scanning Electron Microscope), and EDX. According to the SEM images the particles are spherical in shape with an average size of 89.59 nm. The antibacterial activity was done with 3 bacterial strains i.e., E. coli, Pseudomonas aeruginosa and Bacillus subtills. Antioxidant activity was evaluated by DPPH and phosphomolybdate assays, the calculated IC50 was 85.18±0.55 μg/ml and 66.4±1.3 μg/ml respectively. The calculated IC50 value for alpha amylase assay was 46.59±2.81 μg/ml. As per the outcomes it is concluded that the plant mediated titanium nanoparticle is very potent which can be used in pharmaceutical and biomedical areas.
