Abstract
Three novel sulphated polyhydroxylated steroids, named asterasterols A -C (1-3), have been isolated from an Antarctic starfish of the family Asteriidae and their structures elucidated by spectroscopic studies. S teroid 1 has the seven-membered 5-oxalactone B-ring; 2 and 3 are the c orresponding 6-oxo steroids. (C) 1997 Published by Elsevier Science Lt d.
