The effect of CAE treatment on the viability of differentiated PC12 and IMR32 cells.
Group CAE concentration (mg/mL)
0 25 50 100
Cell viability (%)
PC 12 24 h 100.3 ± 6.2 119.3 ± 4.9* 90.5 ± 3.5** 85.5 ± 0.5**
IMR32 102.2 ± 1.6 109.2 ± 2.4* 112.4 ± 2.5* 121.2 ± 2.6*
PC 12 48 h 100.2 ± 5.9 101.4 ± 4.5 96.9 ± 0.4** 96.9 ± 6.2**
IMR32 103.3 ± 3.1 109.1 ± 2.2 120.8 ± 4.1* 133.3 ± 3.1*
*P < 0.05 compared to control; increase in cell viability. **P < 0.05 compared to control, decrease in cell viability.
CAE: Centella asiatica 20% ethanol extract.
