QP water extract attenuated 6-OHDA-induced apoptosis in PC12 cells. (a) Effects of QP water extract (0.5 mg/mL) on the changes of mitochondrial membrane potential induced by 6-OHDA (500 M). (b) Statistical analysis of the red/green fluorescence intensity ratio, namely mitochondrial membrane potential, expressed as the percentage of control. Data were expressed as means SEM of three separate experiments; versus control and versus 6-OHDA alone group.
