The intestines of freshly caught Saccobranchus fossilis (a freshwater fish that contains dehydroretinol) became free from carotenoids and from vitamin A when the fish were starved for about 20 days. When beta-carotene was administered to such fish, retinoic acid could be isolated from the intestines after approx. 4h. When lutein was administered to such fish, dehydroretinol and 3-hydroxyretinol could be isolated from the intestines after approx. 5h.
刚捕获的黄鳝(一种含有脱氢视黄醇的淡水鱼)在饥饿约20天后,其肠道中的类胡萝卜素和维生素A消失。当给这些鱼投喂β-胡萝卜素时,约4小时后可从肠道中分离出视黄酸。当给这些鱼投喂叶黄素时,约5小时后可从肠道中分离出脱氢视黄醇和3-羟基视黄醇。
