title: [Study on constituents in rhizome of Astilbe chinensis].
abstract: OBJECTIVE
  To study the chemical constituents in rhizome of Astilbe chinensis.
  
  
  METHODS
  The constituents were isolated with column chromatographies and the structures were identified by physicochemical properties and spectral analysis (UV, IR, MS, 1H-NMR, 13C-NMR and 2D-NMR).
  
  
  RESULTS
  The structures were identified as bergenin (1), 11-O-galloylbergenin (2), 4-O-galloylbergenin (3), catechin (4), respectively.
  
  
  CONCLUSIONS
  Compound 3 was isolated from Astilbe for the first time.
