Assessment of the antioxidant activities of representative optical and geometric isomers of astaxanthin against singlet oxygen in solution by a spectroscopic approach

[Display omitted] •Astaxanthin isomer antioxidant activities against 1O2 can be assessed by using DPBF.•The astaxanthin 1O2 quenching capacity is three orders of magnitude greater than that of vitamin E.•The 1O2 quenching capacities of the optical isomers of all-trans-astaxanthin are identical.•The...
