摘要：

Four new polyhydroxysterols, (24S)-ergost-25-ene-1-beta,3-beta,5-alpha,6-beta-tetraol [12], (24S)-ergostane-1-beta,3-beta,5-alpha,6-beta,18,25-hexaol 25-monoacetate [14], (24S)-ergostane-3-beta,5-alpha,6-beta,25-xi,26-pentaol 25-monoacetate [16], and gorgostane-1-beta,3-beta,5-alpha,6-beta,25-pentaol [19], besides the known polyhydroxysterols 1, 3, 5, 7, and 10, were isolated from the soft coral Sarcophyton subviride of Katchal Island of Andaman and Nicobar coasts. Structure elucidation of the new compounds was performed through spectral analysis of their peracetyl derivatives 13, 15, 17, and 20; therefore the possibility of partial acetylation in natural sterols could not be ruled out.
