title: [Chemical constituents of Changium smyrnioides].
abstract: OBJECTIVE
  To study chemical constituents of Changium smyrnioides Wolff.
  
  
  METHODS
  The chemical components were isolated and purified by silica gel column and recrystallization. The chemical structures were elucidated on the basis of physico-chemical properties and spectral data.
  
  
  RESULTS
  Ten compounds were isolated and identified as lignoceric acid (1), beta-sitosterol (2), stigmasterol (3), 5-hydroxy-8-methoxypsoralen (4), glycerylmonopalmitate (5), L-pyroglutamic acid (6), succinic acid (7), vanillic acid-4-O-beta-D-glucopyranoside (8 ), vanillic acid (9), daucosterol (10).
  
  
  CONCLUSIONS
  Compounds 1, 4, 5, 6, 8 and 9 are obtained from the plant for the first time.
