Survival and ROS/RNS production under UV-C-induced oxidative stress conditions. (a) Survival assay, plates were incubated at 28 °C for 3 d and the number of colonies was counted; excepted if mentioned CTL was DBY746 yeast subjected to UV-C stress. (b) ROS/RNS production was evaluated using the dihydrorhodamine 123 (DHR123) probe. AE, almond extract (1 mg/mL). CHL: chlorogenic acid at 3 concentrations (CHL5, CHL10 and CHL25 corresponding to chlorogenic acid addition at 5, 10 and 25 µM, respectively). E-Resveratrol (RES, 10 µM) was used as control antiaging drug. Values are means ± standard deviations (SD) of 6 independent experiments. Different letters represent significant differences between the various extraction conditions (p < 0.05).
