In continuation of our studies on the metabolites of echinoderms of cold waters of the South Atlantic we have investigated the ethanolic extract of three ophiuroid species, Ophiactis asperula (Philippi, 1858), Ophiacantha vivipara (Ljungman, 1870) and Gorgonocephalus chilensis (Philippi, 1858). Ophiactis asperula (Philippi, 1858), Ophiacantha vivipara (Ljungman, 1870) and Gorgonocephalus chilensis (Philippi, 1858). Ophiuroids are characterized by their content of polar sulfated steroidal polyols. Surprisingly, the content of these secondary metabolites proved to be very low in the three species studied. On the other hand, a mixture of nucleosides and nucleobases was found to be the major component of the three ethanolic extracts. Nucleosides and nucleobases composition of the three studied ophiuroid species are reported here for the first time.
