Alcyonacean metabolites VII--chemical constituents of Lobophytum denticulatum and Lobophytum strictum of the Indian Ocean.
A rare cembranoid diterpene, (7E,11E.1 R,2S,3R,4R,l4S)-14-acetoxy-3,4-epoxycembra-7,11,15-triene-17,2-olide (1), was isolated from Lobophytum denticulatum and a new polyhydroxysterol, 7-hydroxyandamansterol (9) has been identified as peracetyl derivative from Lobophytum strictum. Several known polyhydroxysterols have also been isolated from these organisms. 1 exhibited moderate antibacterial activity.
