摘要：

Three new C29 steroids, xestokerols A [1], B [2), and C [3], including a cyclopropane ring in the side chain, have been isolated from the Okinawan marine sponge Xestospongia sp. and the structures elucidated on the basis of spectral data. Xestokerols A and B are very rare C-20-oxidized steroids from marine origin.
