title: [Chemical constituents of Rheum wittrochii Lundstr(II)].
abstract: OBJECTIVE
  To study the chemical constituents in the root of Rheum wittrochii.
  
  
  METHODS
  Chromatography and spectroscopic analysis to isolate and elucidate the chemical constituents in the plant.
  
  
  RESULTS
  Six compounds, namely 3, 5-dihydroxy-4'-methoxystilbene; 3, 5, 4'-tridroxystilbene; piceatannol; desoxyrhaponticin; piceatannol-4'-O-beta-D-glucopyranoside; 2, 5-dimethyl-7-hydroxychromone, have been isolated from ethyl ether and ethyl acetate fractions.
  
  
  CONCLUSIONS
  These compounds were isolated from the title plant for the first time.
