Mycosporine-like amino acid content in the sea anemones Aulactinia marplatensis, Oulactis muscosa and Anthothoe chilensis

The occurrence of mycosporine-like amino acids (MAAs) in the sea anemones Aulactinia marplatensis (Zamponi, 1977), Oulactis muscosa (Drayton in Dana, 1846) and Anthothoe chilensis (Lesson, 1830), from the rocky intertidal habitats on the coast of Mar del Plata, Argentina, was assessed by HPLC.

Descrição
Resumo:The occurrence of mycosporine-like amino acids (MAAs) in the sea anemones Aulactinia marplatensis (Zamponi, 1977), Oulactis muscosa (Drayton in Dana, 1846) and Anthothoe chilensis (Lesson, 1830), from the rocky intertidal habitats on the coast of Mar del Plata, Argentina, was assessed by HPLC. The pattern of MAAs in the mussel Brachidontes rodriguezi, main component of the diet for A. marplatensis and O. muscosa, was as well determined. The results were comparatively analyzed together and with previously reported MAA content in species mainly of the genus Anthopleura. The correlation between the MAA concentration and light availability of their habitats is in line with the photoprotective role assigned to the compounds. The high proportion of mycosporine-taurine in the three species and the results for the evaluation of MAAs in the mussels point to a non-dietary origin or a regulated biotransformation metabolism of dietary MAAs and/or their precursors that is common to sea anemones.
