Sterol constituents of asteroids, Asterias amurensis, Asterina pectinifera, Luidia quinaria, Asteropecten scoparius, Asteropecten polyacanthus, and Coscinasterias acutispina were investigated from the comparative biochemical point of view. They all had similar sterol components of characteristic ?? ⁷-sterols.
?? ⁷-Cholestenol was the major sterol (about fifty percent of total sterols) in these animals. ?? ^7.22-Ergostadienol, ?? ⁷-stigmastenol, and ?? ^7.22-stigmastadienol were also identified by comparing the retention times of GLC with those of authentic samples, and the occurrence of C₂₈ sterol, stellastenol, was recognized in all starfishes investigated.
