The representative contour plots of six groups and the quantitative statistical chart. SCC-25 cells were treated with HLJDD 5 mg/mL, HLJDD 2.5 mg/mL, HLJDD 1.25 mg/mL, paclitaxel 6 μg/mL and cisplatin 5 μg/mL for 24 h. Late stage of apoptosis determined by DxFLEX flow cytometry analyzer following Annexin V FITC and Propidium Iodide (PI) staining. Both Annexin V FITC and PI positive cells represented that the cells were in late stage of apoptosis. The statistics were expressed as Mean ± SEM, n = 3. *** p < 0.001, ** p < 0.01 vs. control group. ### p < 0.001, ## p < 0.01 vs. paclitaxel group. There were no significant differences between other groups and cisplatin group
