Abstract

In the present study one such species, Wedelia trilobata, has be chosen to review the In vitro antibacterial activity of the root extract by using solvent ethanol for the selected plant Wedelia triolobata. The deduction of nanoparticles used to be unalterable by UV-Visible spectroscopy, FTIR, particle size, and zeta potential. The anti-bacterial activity of Wedelia trilobata mediated synthesis silver nanoparticles was tested by disc diffusion assay against standard organisms like Escherichia coli and staphylococcus aureus bacteria. The formation of silver nanoparticles by Wedelia trilobata was initially demonstrated by color changes confirmed by UV-Visible root exhibited a specific absorbance peak around 450 nm and leaf exhibited a specific absorbance peak around 418nm respectively. The Zeta potential of silver nanoparticles was found to be root 0.1 and leaf 0.4, so it indicates the dispersion and stability. The antibacterial activity against Gram-positive Staphylococcus aureus was increased, which was indicated by an increase in the inhibition zone diameter from 3Mm for normal (9.5Mm), standard (12.3Mm), control (11.3Mm), extraction for AgNPs Wedelia trilobata (13.8). 5Mm for normal (7.3Mm), standard (19.4Mm), control (10.5Mm), extraction for AgNPs Wedelia trilobata (19.8). The antibacterial activity against Gram-negative E.coli was increased, which was indicated by an increase in the inhibition zone diameter from 3Mm for normal (7.8Mm), standard (8.5Mm), control (10.2Mm), extraction for AgNPs Wedelia trilobata (14.3). 5Mm for normal (13Mm), standard (19.6Mm), control (15.3Mm) extraction for AgNPs Wedelia trilobata (19.8). The present investigation revealed that the ethanolic Root and aqueous leaf extracts the chosen plant have potential to suppress the expansion of infective bacterial strains.
