found that the combination effect of air and light was more detrimental than light alone while the absorption of curcumin in water had no apparent effect on curcumin photo-stability [79]. In another study, the order of photochemical stability of different curcuminoid complexes in air-sparged conditions in methanol was curcumin > demethoxycurcumin > bis demethoxycurcumin
It was probable that the significant protective or destabilizing effect of different solvents could be ascribed to the formation of inter and
