Three novel polyhydroxysteroid constituents have been isolated from the starfish Styracaster caroli collected at a depth of 2000 m off New Caledonia. These, designated carolisterols A - C (1 - 3), are characterized by a polyhydroxycholanic acid moiety, in which the 24-carboxylic acid function is found as an amide derivative of D-cysteinolic acid.

Abstract
Three novel polyhydroxysteroid constituents have been isolated from the starfish Styracaster caroli collected at a depth of 2000 m off New Caledonia. These, designated carolisterols A - C (1 - 3), are characterized by a polyhydroxycholanic acid moiety, in which the 24-carboxylic acid function is found as an amide derivative of D-cysteinolic acid.File in questo prodotto:
