Objective To study the chemical constituents of the South China Sea black coral Amtipathes dichotoma. Methods Compounds were isolated and purified by repeated column chromatography on silica gel and their structures were identified by spectral analyses and compared with literatures. Results Ten compounds were obtained from A. dichotoma and characterized as stigma-7,22-dien-3β,5α,6β-triol (Ⅰ),5,8-epidioxycampesta-6,22-dien-3-ol (Ⅱ),cholesterol (Ⅲ),(2S,3R,4E,8E)-2-N-(2'-hydroxyhexadecanoyl) hexadecasphinga-4,8-diene (Ⅳ),(2S,3R,4E)-2-N-(2'-hydroxytetracosanoyl) octadecasphinga-4-ene (Ⅴ),batyl alcohol (Ⅵ),thymine (Ⅶ),thymidine (Ⅷ),uracil (Ⅸ),and guanine (Ⅹ). Conclusion All compounds are obtained from Amtipathes dichotoma. for the first time.
