Sensitivity of HepG2 cells to delisheng determined by the MTT assay. After the treatment with 12.5, 25, 50, 100 and 200 μL/mL delisheng for 48 h, the cells in three-dimensional cell culture and monolayer culture were cultured with MTT solution and cell inhibition ratio was determined. The cells in monolayer culture were more sensitive to delisheng (P < 0.01).
