The singlet oxygen quenching ability of various naturally occurring carotenoids was examined by measuring toluidine blue-sensitized photooxidation of linoleic acid. To assess quenching, the oxidation of linoleic acid was followed by measuring oxygen consumption and ultraviolet absorbance at 235 nm. We found that oxygen quenching increased as the number of conjugated double bonds in the carotenoids increased, but quenching varied with chain structure and functional groups. Acyclic carotenoids…

Hydroxyl radical scavenging activity of fucoxanthin and fu Coxanthinol compared with halocynthiaxanthin is assumed to be due to presence of the allenic bond, and ESR analysis of the superoxide radical scavenge activity showed the superiority of fuoxanthin over the other two carotenoids tested.

Results obtained under photo-oxidative stress conditions with strains impaired in carotenoid synthesis suggest that sphaeroidene and neurosporene provide less protection against methylene-blue-generated singlet oxygen than sphaenone in vivo, and it is suggested that singletoxy acts as a specific signal for gene expression in R. sphaeroides.

Major nutritional effects of astaxanthin, such as cardio-, skin-, and ocular-protective effects, are based on its in vivo antioxidant activity, however, the antioxidant activity of fucoxanthin is not largely involved in its characteristic nutritional activity and anti-obesity andanti-diabetic effects.

The data indicate that in vitro irradiation of hepatic microsomes prepared from HPD-treated rats results in the generation of both singlet oxygen and hydroxyl radical, which may explain the unique susceptibility of membranous components of cells to this type of phototoxic injury.
