The color of red tilefish, Branchiostegus japonicus japonicus, fades rather quickly after the catch, so the fish loses its appearance before being sold in the market. For the purpose of elucidating the above phenomenon, carotenoides of the fish were studied. They were separated into six types by column chromatography. Besides the tunaxanthin, a group of seemingly new carotenoids were found, these were provisionally named tilefishxanthin I (diol α-carotene type), tilefishxanthin II (monoketo type of the former), tilefishxanthin III (diketo diol β-carotene type), and tilefishxanthin IV (diketo diol α-carotene type). Tilefishxanthin III (40.2-49.9%) was dominant among them, followed by tunaxanthin (17.3-34.8%), tilefishxanthin IV (8.3-20.0%), tilefishxanthin I (4.4-11.4%), and tilefishxanthin II (2.3-3.7%).
