A minor C27 sterol, glaucasterol, was isolated from the soft coral Sarcophyton glaucum. Based on the spectroscopic evidence and the correlation to cholestanol and 26-nor-27-homocholestanol, its structure was proposed to be 24 epsilon,25 epsilon-24,26-cyclocholesta-5,22E-dien-3 eta-ol (1), the first example of a natural C27 sterol having a cyclopropane ring in the side chain.
