G-Rg6 demonstrates antibacterial effects and bactericidal effects against P. gingivalis strains. P. gingivalis strains were injected into TSA hemin menadione medium at a concentration of 1 × 10² colony-forming units (CFU)/mL. (A) MIC analysis was performed by processing the indicated concentration of G-Rg6 (1, 2, 5, 10, 20, 40, 80, 100 μM). Then, for MBC analysis (B), the 100 μM concentration group of the ginseng-derived natural product cultured in the MIC analysis was serially diluted to create concentration groups of 20, 40, 80, and 100 μM, which were cultured and analyzed again. The antibacterial effects were measured by MIC and MBC. Absorbance wavelength was analyzed at 600 nm.
