Twenty-three flavonoids have been identified in the aerial parts of barrel medic, and their structureswere established by spectrometric and spectroscopic (ESI-MS/MS and NMR) techniques. Eight ofthe identified compounds, including apigenin 7-O-

Additionally, thepresence of two luteolin, three apigenin, one chrysoeriol, and six tricin glycosides, previously identifiedin alfalfa (Medicago sativa), was confirmed in M. truncatula. Moreover, besides the above flavones,the aerial parts of this species contained three flavonols including rutin, laricitrin 3,7,5'-triglucoside,and laricitrin 3,5'-diglucoside.
