Induction of QR-specific enzymatic activity in Hepa-1c1c7 cell line (a). QR assay and viability assay of Hepa1c1c7 cells treated with P. alkekengi (b) physalin A, (c) physalin O, (d) luteolin, (e) methyl chlorogenic acid, and (f) luteolin-7-O-glucoside. (g) QR assay and viability assay of sulforaphane-treated Hepa-1c1c7 cells. The cells treated for 24 h with 5 μM sulforaphane as a positive control.
