title: [Chemical constituents from sea cucumber Holothuria nobilis].
abstract: OBJECTIVE
  To study the chemical constituents of sea cucumber Holothuria hilla L..
  
  
  METHODS
  Compounds were isolated from the sea cucumber by multi-chromatography on Si gel, ODS Rp C-18 gel, DA101 resin, Sephadex LH-20 and HPLC. The structures were elucidated according to their spectral data and chemical character.
  
  
  RESULTS
  Four compounds were isolated from the sea cucumber, and were identified as: holothuria A (I), thymine (II), uracil (III), cholesterol (IV).
  
  
  CONCLUSIONS
  Compounds I IV are obtained from this kind of sea cucumber for the first time.
