QHG and SM/FL alleviated oxidative stress response induced by H₂O₂. ARPE-19 cells were pretreated with SM/FL or QHG for 24 h, and then the cells were further incubated with H₂O₂ for 6 h and ROS was detected by Reactive Oxygen Species Assay. a Images and (b) quantification of dihydroethidium (DHE) staining for intracellular ROS, the original objective magnification is 10 × . Data are presented as the means ± SD of 3 independently repeated experiments (* compared H2O2 group with control, # compared H₂O₂ with H₂O₂ + SM/FL, H₂O₂ + QHG group *, # p < 0.05; **, ## p < 0.01 ***, ### p < 0.001)
