title: New 3beta,5alpha,6beta-trihydroxysteroids from the octocorals Bebryce sp. (Plexauridae) and Carijoa sp. (Clavulariidae).
abstract: A new 3beta,5alpha,6beta-trihydroxysteroid, bebryceoid A (1), has been isolated from an octocoral Bebryce sp. In addition, an octocoral Carijoa sp. yielded two new 3beta,5alpha,6beta-trihydroxysteroids, carijoids A (2) and B (3). The structures of steroids 1-3 were elucidated by spectroscopic methods and by comparison of the spectral data with those of known steroid analogues.
