Echinacoside Alleviates UVB Irradiation-Mediated Skin Damage via Inhibition of Oxidative Stress, DNA Damage, and Apoptosis
Echinacoside suppressed intracellular ROS generation. (a) Cells were pretreated with echinacoside (25, 50, and 100 μM) before exposure to UVB (300 mJ/cm2) irradiation. And 24 h later with UVB irradiation, DCFHDA (10 μM) was introduced into the cells, and fluorescence was measured by flow cytometry. (b) DCFH-DA fluorescence was measured by confocal microscopy. Data are presented as means ± SD (). ## versus control group, versus UVB group.
