title: [Studies on chemical constituents from leaves of Sapium sebiferum].
abstract: OBJECTIVE
  To study the chemical constituents from leaves of Sapium sebiferum.
  
  
  METHODS
  The compounds were isolated and purified by silic gel column chromatography and preparative HPLC. The structures were identified by various spectral evidence.
  
  
  RESULTS
  Nine compounds were obtained and they were shikimic acid (1), kaempferol (2), quercetin (3), isoquercein (4), hyperin (5), kaempferol-3-O-beta-D-glucopyranoside (6), kaempferol-3-O-beta-D-glueopyranoside (7), gallic acid (8), rutin (9).
  
  
  CONCLUSIONS
  Compounds 1, 5, 6 and 7 are isolated from this genus for the first time and compound 9 is isolated from this plant for the first time.
