title: [Study on the chemical constituents of Curcuma phaeocaulis].
abstract: OBJECTIVE
  To investigate the chemical constituents of the rhizome of Curcuma phaeocaulis Val.
  
  
  METHODS
  The constituents were isolated by column chromatography and their structures elucidated by chemical properties and spectroscopic analysis.
  
  
  RESULTS
  Five compunds have been isolated and identified as isocurcumenol, curcumenol, alpha-spinasterol, curcumin, and beta-sitosterin-3-O-glucoside.
  
  
  CONCLUSIONS
  alpha-Spinasterol and alpha-stediol were isolated from Curcuma phaeocaulis Val. for the first time.
