摘要：

Nine ophiuroid species from different geographical areas have been analyzed for their polar steroid content. Six new sulfated polyhydroxysteroids have been isolated, together with six known compounds of this type previously reported from brittle scars. The new steroids possess C-21 and 3 alpha- sulfate groups, which are distinctive features of the steroid sulfates of ophiuroids. Hydroxylation at C-2, C-4, and C-11 and the presence of double bonds at C-5 are further features of the new steroids. The structures of the new compounds were solved by spectroscopic analysis.
