title: [Studies on flavonoids from Fenugreek (Trigonella foenumgraecum L.)].
abstract: OBJECTIVE
  To study the flavonoids in fenugreek (Trigonella foenumgraecum) produced in China.
  
  
  METHODS
  The flavonoids were isolated with silica gel, polyamide and Sephadex LH-20 chromatography, and their structures were identified by physical, chemical properties and spectral analysis.
  
  
  RESULTS
  Five flavonoid compounds were isolated from fenugreek seeds and identified as vitexin, tricin, naringenin, quercetin and tricin-7-O-beta-D-glucopyranoside.
  
  
  CONCLUSIONS
  Three flavonoids, tricin, naringenin and tricin-7-O-beta-D-glucopyranoside, were isolated from fenugreek as well as from the plants of Trigonella for the first time.
