Synergistic Antioxidant Effects of Araloside A and L-Ascorbic Acid on H₂O₂-Induced HEK293 Cells: Regulation of Cellular Antioxidant Status

Figure 4

Individual and combined effect of araloside A and L-ascorbic acid () on reactive oxygen species (ROS) generation. (a) Fluorescence images in HEK293 cells were collected by laser scanning confocal microscopy (LSCM) 200x. (A) Control group; (B) injury group; (C) ; (D) ; (E) ; (F) ; (G) H₂O₂; (H) ; (I) ; (J) ; (K) . (b) Production of intracellular ROS was measured using the fluorescence probe 2,7-dichlorodihydrofluorescein diacetate (DCFH-DA). Vertical bars indicate the . ^## versus the araloside A+L-ascorbic acid group. versus the injury group.
