Reactions between a carotenoid, fucoxanthin and 1,1‐diphenyl‐2‐picrylhydrazyl were investigated both under anoxic and aerobic conditions. Fucoxanthin equimolarly reacted with 1,1‐diphenyl‐2‐picrylhydrazyl under anoxic conditions. Under aerobic conditions, only a part of fucoxanthin consumed 1,1‐diphenyl‐2‐picrylhydrazyl and the degree of reaction fluctuated with repeated trials. β‐Carotene or other carotenoids, β‐cryptoxanthin, zeaxanthin, licopen and lutein, were also examined in the reaction with 1,1‐diphenyl‐2‐picrylhydrazyl under anoxic conditions. All these compounds scarcely reacted with 1,1‐diphenyl‐2‐picrylhydrazyl.
