  Three new polyhydroxysteroids from the tropical starfish Asteropsis carinifera

  摘要：

  Thirteen steroidal compounds including three new polyhydroxysteroids, (24R,25S)-24-methyl-5 alpha-cholestane-3 beta,6 alpha,8,15 beta,16 beta,26-hexaol, (22E,24R,25S)-24-methyl-5 alpha-cholest-22-ene-3 beta,6 alpha,8,15 beta,16 beta,26-hexaol, and (22E,24R,25S)-24-methyl-5 alpha-cholest-22-ene-3 beta,4 beta,6 alpha,8,15 beta,16 beta,26-heptaol, have been isolated along with ten previously known polyhydroxysteroids from the tropical starfish Asteropsis carinifera collected near the coast of Vietnam. The structures of the new compounds were elucidated by spectroscopic methods (mainly 2D NMR and ESI mass spectrometry).
