Effect of baicalein on the viability of A431 cells. a. Structure of baicalein, which is the aglycone compound of baicaline. b. A431 cells were treated with 0, 2.5, 5, 10, 20, 40, 50, or 60 μM of baicalein for 48 h before being subjected to an MTT assay for cell viability. Data were represented as the mean ± SD from three independent experiments. Baicalein had no cytotoxic effect on A431 cells at a range of 2.5-40 μM. Results were statistically analyzed with a Student's t-test (*p < 0.05). The error bars represent SDs.
