SYNOPSIS. The pigments synthesized by Astasia ocellata include α‐ and ε‐carotene, 4‐keto‐β‐carotene (echinenone), and 4,4′‐diketo‐β‐carotene (canthaxanthin); 4‐keto‐α‐carotene, accounting for about half the pigment in the cells, was tentatively identified; a strongly adsorbed keto‐carotenoid, accounting for 25% of the pigments and bearing some similarities to astacin, polytomaxanthin and phoenicoxanthin, was also found.
