Embelin-induced apoptosis of HepG2 human hepatocellular carcinoma cells. (A) Annexin V/PI dye was used to determine the rate of apoptosis after HepG2 cells were treated with different doses of embelin (0, 40, 80 and 120 μg/ml) for 48 h. (B) The histogram shows the HepG2 apoptosis rate (%).^*P<0.05, ^**P<0.01. The data are representative of three independent experiments
