title: [Studies on the chemical constituents of the leaves of Polygonum multiflorum].
abstract: OBJECTIVE
  To study the chemical constituents of the leaves of Polygonum multiflorum.
  
  
  METHODS
  The chemical constituents were extracted with water and separated by manifold chromatography technique, and their structures were determined by spectral analysis.
  
  
  RESULTS
  Eleven compounds were isolated and identified as physcion (I), emodin (II), noreugenin (III), apigenin (IV), hyperoside (V), rutin (VI), vitexin (VII), 2,3,5 ,4'-tetrahydroxy-stibene-2-O-beta-D-glucoside (VIII), beta-amyrin (IX), beta-sitosterol (X), daucosterol( XI).
  
  
  CONCLUSIONS
  Among these compounds, I - IV, VI - XI are isolated from the leaves of Polygonum multiflorum for the first time.
