Anti-biofilm activity of 10 selected compounds of natural origin against H. pylori J99. The amount of biofilm under stationary conditions was determined using the crystal violet staining method. The study was performed with triplicate biological replications (n = 3). The p-value represented by ns, *, **, ***, and **** is equal to > 0.05, < 0.05, < 0.01, < 0.001, and < 0.0001, respectively.
