Dicitrinone B induces the accumulation of reactive oxygen species (ROS). (A) After dicitrinone B (five, 10 and 20 μM) treatment for 24 h, the level of intracellular ROS using DCF fluorescence was detected by flow cytometry, with 5-Fu (100, 200 and 400 μM) as a positive control. (B) Quantification of the results shown in (A). Values are expressed as the mean ± SD of three independent measurements. Significant differences between the treatment and control groups are indicated as * (p < 0.05) or ** (p < 0.01).
