title: [Study on the chemical constituents from Melicope ptelefolia].
abstract: OBJECTIVE
  To study the chemical constituents from Melicope ptelefolia.
  
  
  METHODS
  Several chromatographic methods were applied to isolate and purify compounds. Their structures were identified on the basis of physicochemical properties and spectroscopic data.
  
  
  RESULTS
  Seven compounds were isolated and elucidated as n-octadecanyl palmitate (I), beta-sitosterol (II), palmitic acid (III), 3, 5,3'-trihydroxy-8,4'-dimethoxy-7-(3-methylbut-2-enyloxy) flavone (IV), daucosterol (V), salylic acid (VI), kaempferol-3-O-alpha-D-arabinpyranoside (VII).
  
  
  CONCLUSIONS
  Compound VII is isolated from the genus for the first time, Compounds V and VI are isolated from Melicope ptelefolia for the first time.
