title: [Studies on the chemical constituents of Rhodiola rosea].
abstract: OBJECTIVE
  To separate and identify the chemical constituents of n-BuOH extraction from the roots of Rhodiola rosea in Xinjiang.
  
  
  METHODS
  The column chromatography was used to separate consituents. The structures were elucidated by chemical reactions and MS, 1H-NMR, 13C-NMR, and 2D-NMR spectral data.
  
  
  RESULTS
  Six compounds were isolated and identified as salidroside (I), kaempferol-7-O-alpha-L-rhamnopyranoside(II), herbacetin-7-O-alpha-L-rhamnopyr-anoside(III), herbace-tin-7-0-(3"-O-beta-D-glucopyran-oside)-alpha-L-rhamnopyranoside(IV), 5, 7, 3', 5'-tetrahydroxy-flavanone(V), sucrose(VI).
  
  
  CONCLUSIONS
  Compound V is isolated from this plant for the first time.
