OBJECTIVE: To evaluate the anti-bacterial activities of titanium dioxide (TiO) nanoparticles of Origanum (O.) vulgare and Hypericum (H.) perforatum extracts, carvacrol and hypericin against Staphylococcus (S.) aureus.
METHODS: In this study, TiOnanoparticles of O. vulgare and H. perforatum extracts, carvacrol and hypericin, were prepared and their antibacterial effects were evaluated against Staphylococcus (S.) aureus. In this study, scanning electron microscope, fourier transform infrared spectrometer, atomic force microscopy, dynamic light scattering and zeta potential were used to investigate the structure of synthesized drugs.
RESULTS: Anti-bacterial activity of synthesized NPs was tested by minimum inhibitory concentration (MIC), minimum bactericidal concentration and disc diffusion method. MICs of TiO-NPs synthesized using O. vulgare, H. perforatum, carvacrol and hypericin and TiO were obtained 250, 62.5, 250, and 250, and 500 μg/mL, respectively. The MBCs for all of these were obtained 1000 μg/mL.
CONCLUSION: Green-synthesized of TiO nanoparticles provides a promising approach to the use of O. vulgare and H. perforatum, carvacrol and hypericin as novel agents and safer antibacterial compounds, especially anti-S. aureus compounds.
