Protective effect of curcuminoids on epidermal skin cells under free oxygen radical stress
Planta Medica
|June 1, 1997
Abstract:
Curcuminoids from Curcuma longa L. (Zingiberaceae) protected normal human keratinocytes from hypoxanthine/ xanthine oxidase injury. Since curcuminoids synergistically inhibited nitroblue tetrazolium reduction, a decrease in superoxide radical formation leading to lower levels of cytotoxic hydrogen peroxide was proposed as an explanation for this protective effect.
