ROS production (a, b) and viability (c) of the ARPE-19 cells. a, b: The ImageJ software was used to measure the intensity of the fluorescence. The rate of production of ROS in the LD group (84.94 ± 3.29%) increased by 45.92% (P < 0.001) compared with that in the control group (58.21 ± 6.46%); the rate in the LC (76.62 ± 4.40%) and HC (61.56 ± 2.02%) groups decreased by 10.5% (P < 0.05) and 27.53% (P < 0.0001), respectively, compared with that in the LD group. c: After treatment with the chrysanthemum extract before light damage, the cell viability rate in the LC and HC groups increased to 69.22 and 76.04%, respectively, compared with that in the LD group (P < 0.05 and P < 0.001); the data were analysed using one way-ANOVA. *P < 0.05, **P < 0.01, ***P < 0.0001
