“Pre-incubation with lutein, zeaxanthin , or α-tocopherol dramatically reduced the levels of H2O2 -induced protein carbonyl, MDA, and DNA damage in HLEC.”
“ Zeaxanthin also inhibited the neurotoxicity induced by H2O2 or serum deprivation and scavenged the intracellular radicals induced by H2O2 or serum deprivation.”
“In chill-stressed plants, zeaxanthin treatment also enhanced antioxidant enzyme activity and transcript expression, and reduced hydrogen peroxide (H2O2) and superoxide anion (O2•-) content, resulting in a decrease in biological membrane damage.”

“Pretreatment of zeaxanthin also reduced intracellular MDA content caused by H2O2 stimulation from 0.86 µmol/L to 0.52 µmol/L (P=0.02) in limbal epithelial cells and from 0.96 µmol/L to 0.56 µmol/L in conjunctival epithelial cells (P=0.03).”
