(A) Effect of byakangelicol, imperatorin, and isoimperatorin on the cell growth of HeLa cells. (B) Hoechst 33,258 staining of byakangelicol, imperatorin, and isoimperatorin on HeLa cells and DMSO treatment group was used as control. Scale bar = 200 μm. (C) Apoptotic effects of byakangelicol, imperatorin, and isoimperatorin on HeLa cells. Cells were incubated with the different concentrations for 48 h and detected using Annexin V-FITC/PI staining by flow cytometry. Data are presented as mean ± SD (n = 3). ∗P < 0.05, ∗∗P < 0.01, and ∗∗∗P < 0.001 vs. control group.
