Abstract

The existence of canthaxanthin, 4-hydroxy-echinenone, 3-hydroxy-canthaxanthin and astaxanthin in the carapaces of the lobster, Panulirus japonicus was confirmed. 2. ^-Carotene, /3-zeacarotene, echinenone, isocryptoxanthin and astaxanthin were found in the internal organs. 3. It was proposed that in the lobster, dietary /3-carotene is converted to astaxanthin through the steps of isocryptoxanthin, echinenone, 4-hydroxy-echinenone, canthaxanthin and 3-hydroxy-canthaxanthin as follows: /S-carotene-> isocryptoxanthin — echinenone-> 4-hydroxy-echinenone - canthaxanthin-> 3-hydroxy-canthaxanthin —* astaxanthin. © 1973, The Japanese Society of Fisheries Science.
