Abstract
Composition of steroid sulfates from starfish Pteraster tessellatus an d Pteraster spl is reported. 2,21-Disulfate of cholest-5-ene-2 beta,3 alpha,21 triol 1) and 3,21-disulfates of cholest-5-ene-2 beta,3 alpha, 21-triol 2) and cholest-5-ene-3 alpha,4 beta,21-triol 3) were found in both species. These steroids are characteristic secondary metabolites of ophiuroids and have not been isolated previously from Asteroidea ( starfish) or other taxa. Phylogenetic relationships between classes As teroidea and Ophiuroids are discussed.
