Influence of V. opulus FJ and PJ preparations on the intracellular reactive oxygen species generation analyzed by DCFH-DA assay in differentiated 3T3-L1 cells (A); control cells were not exposed to any compound; as a positive control for ROS generation, 500 µM t-BOOH was used; values are means ± standard deviations from at least three independent experiments, n ≥ 9; statistical significance was calculated versus control cells * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001. Cells visualized under phase-contrast and fluorescent microscope (200× magnification) (B).
