Paeonol inhibits MPP+-induced cell apoptosis of astrocytes. Compared with the control group, MPP+ obviously increased cell apoptosis of astrocytes, which was dose-dependently inhibited by paeonol (0.75, 1, 1.5 μmol/L) (A). The statistical data are also exhibited (B). ## p<0.01 indicates there was a significant difference between the control group and PD group, * p<0.05 or ** p<0.01 indicates there was a significant difference between the PD group and PD+Paeonol groups.
