title: [Chemical constituents from leaves of Sterculia foetida].
abstract: OBJECTIVE
  To study the chemical constituents from the leaves of Sterculia foetida.
  
  
  METHODS
  Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectroscopic methods.
  
  
  RESULTS
  Eight compounds were identified as 5,7,8-tetrahydroxy-4'-methoxyflavone-8-O-beta-D-glucoside (1), 5,7,8-tetrahydroxy-4'-methoxyflavone-7-O-beta-D-glucoside (2), quercetin-3-O-beta-D-glucoside (3), apigenin-6, 8-di-C-beta-D-glucoside (4), puerarin (5), 5,7,8,3'-tetrahydroxy-4'-methoxyflavone (6), 5,7,8-tetrahydroxy-3',4'-dimethoxyflavone (7), 5,7,8-tetrahydroxy-4'-methoxyflavone (8).
  
  
  CONCLUSIONS
  Compounds 1, 2 and 4-8 were isolated from this plant for the first time.
