Abstract
The CHCl3 extract of the Mediterranean sponge Clathrina clathrus was shown to contain three new sterols: (22 E)-3 beta-hydroxycholesta-5,8,22-trien-7-one (1), (22 E, 24 xi)-3 beta-hydroxy-24-methylcholesta-5,8,22-trien-7-one (2), and (22 E, 24 xi)-3 beta-hydroxy-24-ethylcholesta-5,8,22-trien-7-one (3), whose structures were elucidated on the basis of physico-chemical evidence.
