In the original publication of the article, Fig. 1C was published incorrectly. The correct version of Fig. 1 is provided in this correction.

Physalin A (PA) induced growth inhibition and reactive oxygen species (ROS) generation in human non-small-cell lung cancer A549 cell. A Chemical structure of PA. B A549 cells were treated with various doses (0, 12, 16, 21.3, 28.4, and 38 µM) of PA for 3, 6, 12, and 24 h. Cell growth inhibition rate (%) was measured using the MTT assay. Data are shown as mean ± standard deviation (SD) from three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001 versus controls (0 µM PA) at the same time point. C A549 cells were cultured with 28.4 µM PA for 0, 3, 6, 12, and 24 h in the absence or presence of 3 mM N-acetylcysteine (NAC), the ROS scavenger. The generation of ROS was measured by flow cytometry using the ROS-detecting fluorescent dye DCF-DA. Data are shown as mean ± SD from three independent experiments. *P < 0.05, **P < 0.01, and ***P < 0.001 versus control group (28.4 µM PA for 0 h); ^##P < 0.01 versus A549 cells treated with 28.4 µM PA for 24 h
