title: [Studies on the chemical constituents of the ethyl acetate portion of Nervilia fordii].
abstract: OBJECTIVE
  To study the chemical constituents of the ethyl acetate portion in the herb of Nervilia fordii from guangxi.
  
  
  METHODS
  The constituents were separated and purified by using column chromatography with silica gel. These compounds were identified by their physical and spectral data.
  
  
  RESULTS
  Five compounds were isolated and identified as norleucine (crystal I), 24 (S/beta)-dihydrocycloeucalenol-(E)-p-hydroxy cinnamate (crystal II) , rhamnocitrin (crystal III), rhamnazin (crystal IV), daucosterol (crystal V).
  
  
  CONCLUSIONS
  Compounds I , II, III, IV, V were isolated from this plant for the first time.
