Chemical studies on the soft coral Lobophytum jaeckel Tix.-Dur.

Four sterols were isolated from the ethanol extract of the soft coral Lobophytum jaeckel Tix.-Dur., collected from the Hainan Island. By spectroscopic analysis. Their structures were identified respectively to be (24S)-24#alpha#-methylcholest-5-en-3#beta#, 25-diol(1), (24S)-24#alpha#-methylcholest-3#beta#, 5#alpha#, 6#beta#, 25-tetrol-25-mono-acetate (2), (24S)-24#alpha#-methyl-cholestane-1#beta#, 3#beta#, 5#alpha#, 6#beta#-tetrol(3), gorgosterol(4).
