Protective effects of Asian green vegetables against oxidant induced cytotoxicity

Figure 3 Effect of green vegetable extracts on QR and GST induction in the human colon HCT116 cell line. Cells were treated with each respective extract at 0.01-1 mg/mL (broccoli and Rorripa) and 1-10 mg/mL Choi Sum, Pa Po, Pheuy leng and Sio Pek for 24 h. (A) induction of QR and (B) GST induction by broccoli and Rorripa, (C) and (D) induction of QR and GST by Choi Sum, Pa Po, Pheuy leng and Sio Pek, (E) Rorripa ITC, 7-methylsulfinylheptyl ITC and (F) broccoli ITC, 4-methylsulfinylbutyl ITC as determined using LC-MS. Each data point represents the mean±SD for four separate experiments. ^bP<0.001 vs the control cells.
