Euretaster insignis

D Auria et al. (654) found two groups of sterol sulfates in the aqueous extract of the starfish Euretaster insignis. Hydrolysis of the less polar fraction gave cholest-7-en-3 P-ol and C26 C27, C28, and C29 5a-steroidal alcohols. The more polar fraction contained sulfated 3p,21-dihydroxysteroids. After solvolysis to remove the sulfate groups the steroids were identified as (20i )-24-methylenecholestane-3P,21-diol (981), (20R)-24-methylenecholest-5-ene-3p,21-diol (982), (20/ ,22 )-24-methylcholest-22-ene-3P,21-diol (983), (20/ )-choles-tane-3p,21-diol (984), (207 ,22 )-cholest-22-ene-3p,21-diol (985), and (207 )-cholest-5-ene-3P,21-diol (986). This starfish was apparently devoid of saponins. [Pg.296]
