Anti-Oxidative Properties of Astaxanthin and Related Compounds
Carotenoids have attracted attention in food and healthcare industries owing to their ability to quench ROS. Here, we present a method for the determination of anti-oxidative property against singlet oxygen (O-1(2)), which plays an important role in skin aging. We quantified the bimolecular O-1(2) quenching rate constant, and the amount of O-1(2) molecules that can be quenched by a single anti-oxidative molecule before degradation, for five materials. We have defined the anti-oxidative property against O-1(2) as the product of these two constants. It was revealed that anti-oxidative properties of astaxanthin and lycopene were the highest among the materials investigated.
