title: [Studies on the chemical constituents from the flowers of Ophiopogon japonicus].
abstract: OBJECTIVE
  To study the chemical constituents from the flowers of Ophiopogon japonicus.
  
  
  METHODS
  Column chromatography and spectral analysis were used to isolate and identify the constituents.
  
  
  RESULTS
  Eleven compounds were obtained and identified as beta-sitosterol (I), diosgenin (II), daucosterol (III), ophiopogonin C' (IV), dioscin (V), 7-dihy-droxy-6-methyl-3-(4'-hydroxybenzyl) chroman-4-one(VI), luteolin (VII), kaempferol-3-O-beta-D-glucopyranosides (VIII), kaempferol-3-O-(6"-tigloyl) -beta-D-glucopyranosides (IX), kaempferol-3-O-(6"-acetyl) -beta-D-glucopyranosides (X), glucose (XI).
  
  
  CONCLUSIONS
  Eleven compounds are obtained from the flowers of O. japonicus for the first time. Compond VI is isolated as a simple substance compound of O. japonicus for the first time. Componds VII, VIII, IX and X are isolated from this genus for the first time.
