[Studies on flavonoids from Fenugreek (Trigonella foenumgraecum L.)]
Abstract
Objective:
To study the flavonoids in fenugreek (Trigonella foenumgraecum) produced in China.
Method:
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.
Result:
Five flavonoid compounds were isolated from fenugreek seeds and identified as vitexin, tricin, naringenin, quercetin and tricin-7-O-beta-D-glucopyranoside.
Conclusion:
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.
