title: [Study on chemical constituents in total saponin from Trigonella foenum-graecum].
abstract: OBJECTIVE
  To study the chemical constituents in the total saponin from Trigonellf foenum-graecum.
  
  
  METHODS
  The compounds were isolated by column chromatography on macroporous resin and silica gel and elucidated by physical and chemical evidences and spectroscopic analysis.
  
  
  RESULTS
  Two compounds were obtained and identifiedas methyl-protodioscin and methyl-protodeltonin.
  
  
  CONCLUSIONS
  Methyl-protodioscin and methyl-protodeltonin were isolated from this plant for the first time.
