title: [Chemical Constituents of Seaweed Sargassum naozhouense].
abstract: OBJECTIVE
  To investigate the chemical constituents in the seaweed Sargassum naozhouense collected from the sea around Zhanjiang.
  
  
  METHODS
  The compounds were isolated and purified by various chromatographic techniques including silica gel chromatography, Sephadex LH-20 gel chromatography as well as preparative thin layer chromatography, and their structures were identified by spectral analysis.
  
  
  RESULTS
  Ten compounds were isolated and identified as 1-O-hexadecanoyl glycerol (1), pheophytin a(2), β-sitosterol (3), mannitol (4), uracil (5), thymine(6),p-hydroxybenzoic acid(7) 3,4-dihydroxybenzoic acid (8) 4-hydroxyphthalide (9), and 2'-de-cxythymidine( 10).
  
  
  CONCLUSIONS
  All the compounds are isolated from the seaweed Sargassum naozhouense for the first time.
