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. beta-Carotene or other carotenoids, beta-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.
在缺氧和有氧条件下，研究了类胡萝卜素岩藻黄质与1,1-二苯基-2-苦基肼之间的反应。在缺氧条件下，岩藻黄质与1,1-二苯基-2-苦基肼等摩尔反应。在有氧条件下，只有一部分岩藻黄质消耗了1,1-二苯基-2-苦基肼，并且反应程度在重复试验中有所波动。还在缺氧条件下检测了β-胡萝卜素或其他类胡萝卜素、β-隐黄质、玉米黄质、番茄红素和叶黄素与1,1-二苯基-2-苦基肼的反应。所有这些化合物几乎都不与1,1-二苯基-2-苦基肼反应。
