  α-tocopherol 17.83±3.85* 0.94±0.21 18.9

HLEC were supplemented with or without 5 µM of lutein, zeaxanthin or α-tocopherol for 48 h and then exposed to 100 µM H2O2 for 1 h. Levels of GSH and GSSG were determined by HPLC. Each value is expressed as mean±SD (n=6), *Indicates a p<0.05 when compared with control groups that were treated with the same level of H2O2.
