Effect of PEF on I/R-induced apoptosis in H9C2 cells. A Density plots of Annexin V-FITC/PI staining are based on flow cytometry analysis of no-treatment control and cells treated with PEF under I/R and normal condition. B Representing the apoptosis rates. Apoptosis decreased significantly when cells were treated with plant extract under I/R condition. The experimental data are from three independent experiments (n = 3). ^*P < 0.05 vs. normal, ^$P < 0.05 vs. I/R
