Effect of Tsoong on the proliferation and cell cycle of HCT116 and SW480 cancer cells. The cells were treated with Tsoong-containing serum solutions prepared from mice treated by gastrogavage with saline (control), or 5 (low), 10 (mid) or 20 (high) g/kg of Tsoong for indicated durations. (A) cell proliferation was detected using a cell counting kit‐8 assay, and (B) cell cycle was detected using flow cytometry. (C) Cell apoptosis was analyzed using flow cytometry. Oxaliplatin was used as a control. P < 0.05 vs. control; P < 0.01 vs. control. Tsoong or cbFeD, Codonopis bulleynana Forest ex diels.
