Representative flow cytometric dotplots of the cell death induction of HepG2 cells treated with Cyperus articulatus rhizome essential oil (EO), as measured by flow cytometry using annexin V-FITC/PI staining. The negative control (CTL) was treated with a vehicle (0.5% DMSO) used to dilute EO, and doxorubicin (DOX, 1 µg/mL) was used as a positive control. Ten thousand events were evaluated per experiment, and cell debris was omitted from the analysis.
