(A, B) Intracellular ROS levels were significantly higher in the H₂O₂ group, as compared with the control. Intracellular ROS levels in the cyanidin-H₂O₂ and the delphinidin-H₂O₂ subgroups were lower than in the H₂O₂ group. The graph represents the mean ± SD of 3 independent experiments (^**p<0.01 compared to control group; ^###p<0.001 compared to H₂O₂ group). (C, D) According to the morphological analyses using a confocal microscope, intracellular ROS levels were higher in the H₂O₂ group than in the control; however, ROS levels were markedly lower in the cyanidin-H₂O₂ and the delphinidin-H₂O₂ subgroups than in the H₂O₂ group. Cya: Cyanidin, Del: Delphinidin.
