title: [Chemical Constituents from Drypetes hainanensis Stems and Leaves].
abstract: OBJECTIVE
  To study the chemical constituents from the stems and leaves in Drypetes hainanensis.
  
  
  METHODS
  The constituents were isolated and purified by various chromatography, and the structures were identified by extensive spectral analysis.
  
  
  RESULTS
  Eleven compounds were isolated and identified as syringaresinol-4-O-glycoside (1), koaburaside (2), abietin (3) syringin (4), kelampayoside A (5), 7,7'-bis-(4-hydroxy-3,5-dimethoxyphenyl)-8,8'-dihydroxymethyl-tetrahydrofuran-4-O-β-glucopyranoside (6), amentoflavone (7), 3,4,5-trimethoxyphenyl-β-D-glucopyranoside (8),1,4-di-O-methyl-myo-inositol (9), glycerol (10) and succinic acid (11).
  
  
  CONCLUSIONS
  All the compounds are isolated from this plant for the first time.
