title: [Chemical Constituents from Claoxylon indicum Stems].
abstract: OBJECTIVE
  To study the chemical constituents of Claoxylon indicum stems.
  
  
  METHODS
  The chemical constituents were isolated, purified and identified by various chromatographic and spectral techniques.
  
  
  RESULTS
  Seven compounds including oleanolic acid (1), 6-amyrin(2), 7-ketositosterol(3), scopoletin(4), β-sitosterol-β-glucoside(5), L-pyroglutamic acid (6) and β-sitosterol (7) were isolated from ethanol extract of this plant stems.
  
  
  CONCLUSIONS
  Compounds 1 - 6 are obtained from this plant for the first time.
