✦ Synopsis

New 26, 27-cyclosterols, aragusterols E-H, were isolated from the Okinawan marine sponge of the genus Xestospongia. Their structures were determined by spectroscopic measurement and chemical conversion. The absolute configurations of xestokerols A and B were determined by chemical conversion.
