Effects of different concentrations of rosmarinic acid on intracellular ROS generation in HaCaT cells. Cells were preincubated with DCFH-DA (10 μM) for 30 min and then washed twice and (a) treated with different concentrations of RA and (b) treated with 100 μM H2O2 and different concentrations of RA. Control cells were treated with the same amounts of the solvent. The number of experiments is 3.
