Figure 8. HepG2 cells were exposed to 0, 16, 32, 64 μmol/l α-pinene, and NAC+64 μmol/l α-pinene for 24 h.

α-pinene induced ROS level increased and pretreated with NAC decreased the ROS level. Results represent three independent experiments. *P<0.05, **P<0.01, and ***P<0.001, n.s: not significant (compared with control).
