title: [Chemical constituents of the roots of Vaccinium bracteatum].
abstract: OBJECTIVE
  To study the chemical constituents of the roots of Vaccinium bracteatum.
  
  
  METHODS
  The constituents were separated and purified with chromatographic methods (including silica gel, Sephadex LH-20 and RP-18 column chromatography), and their structures were determined by spectroscopic methods (including MS, 1H-NMR and 13C-NMR).
  
  
  RESULTS
  10 compounds were isolated from the roots of Vaccinium bracteatu and were elucidated as chlorogenic acid (1), pinoresinol (2), ferulic acid (3), kaempferol (4), trans-caffeic acid (5), beta-sitosterol (6), quercetin (7), oleanolic acid (8), apigenin (9) and luteolin (10).
  
  
  CONCLUSIONS
  Compounds 1 -3 are obtained from this plant for the first time.
