[Study on the chemical constituents of Antipathes dichotoma].

To investigate the chemical constituents of Antipathes dichotoma. The compounds were isolated and purified by column chromatography on silica gel and their structures were identified by spectral analyses and comparison with literatures. Nine compounds were obtained from A. dichotam and characterized as cholesterol (I), ergosta-5-ene-3-ol (II), 4-methyl-ergostatrien-3-ol (III), p-hydroxybenzoate (IV), 3,4-dihydroxybenzaldehyde (V), vanillin (VI), caffeic acid (VII), batyl alcohol (VIII), and theymine (IX). Compounds II - VII are obtained from Antipathes dichotoma for the first time.
