ROS production of CDPs under abiotic and biotic conditions. a Inherent oxidative potential of the three different CDPs at the various concentrations tested in this study. Red line: the background oxidative level in blank cell culture (IMDM) solution was set as reference. Data are represented as means ± SD (n = 3). * Statistically different from control p < 0.05. b Human lung fibroblasts (MRC-5 cell line) were exposed to different concentrations (5–25 µg/cm2) of three different types of CBs for 24 h at 37 °C. At the end of the exposure a DCF-DA assay was conducted to determine ROS production under biotic conditions. All data are represented as means ± SD (n = 3). * Statistically different from control p < 0.0001
