title: Studies on the chemical constituents from the stem and leaves of Tagetes erecta.
abstract: OBJECTIVE
  To investigate the chemical constituents of the stem and leaves of Tagetes erecta.
  
  
  METHODS
  The materials extracted with ethanol were first purified with D101 resin and then separated by repeated silica gel column chromatography as well as recrystallization to get single compounds. The chemical structures of the compounds were elucidated on the basis of physicochemical properties, spectroscopic analysis and comparing with standard sample and literatures.
  
  
  RESULTS
  Six compounds were identified as 4'-methoxy-eupatolitin-3-O-glucoside (I), kaempferitrin (II), rutin (III), beta-sitosterol (IV), daucosterol (V) and gallic acid (VI).
  
  
  CONCLUSIONS
  Compounds I, II, III are isolated from the plant for the first time; the compounds IV, V, VI are isolated from the stem and leaves of the plant for the first time.
