title: [Studies on the chemical constituents in radix Astilbes chinensis].
abstract: OBJECTIVE
  To isolate and determine the chemical constituents from Astilbe chinensis.
  
  
  METHODS
  Four compounds were isolated and purified by extraction and column chromatography on silica gel. The chemical structures were determined on the basis of physical-chemical evidence and extensive spectral analysis(HR-EIMS, EIMS, 13C-NMR, 1H-NMR, DEPT, 1H-1H-COSY, HMQC and HMBC).
  
  
  RESULTS
  Their structures were elucidated as beta-sitosterol palmitate I, daucosterol II beta-sitosterol III and Bergenin IV, respectively.
  
  
  CONCLUSIONS
  Compound I and II were isolated from A. chinensis for the first time.
