[Study on the chemical constituents of Antipathes dichotoma].

OBJECTIVE: To investigate the chemical constituents of Antipathes dichotoma. METHODS: The compounds were isolated and purified by column chromatography on silica gel and their structures were identified by spectral analyses and comparison with literatures. RESULTS: 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). CONCLUSION: Compounds II - VII are obtained from Antipathes dichotoma for the first time.
