 * Identification of parasiloxanthin and its derivative 7,8-dihydroparasiloxanthin, as well as 3'-epilutein and monadoxanthin, are worthy of notice. These carotenoids, except for 3'-epilutein, have hitherto been found in few species and only on the Japanese islands.

 * Monadoxanthin, losing one hydroxyl group, turns into crocoxanthin (one hydroxyl and acetylene bond). The product of reduction of crocoxanthin was not found, and it is a problem for further research
