Four dominant flavonoid compounds in crystal form were isolated from flowers of Medicago lupulina L. and identified as laricytrin (3'-metoxy-3,4',5,5'7-pentahydroxyflavone), and its three glycosides: 5'-O-β-D-glucoside, 3,5'-O-β-D-diglucoside and 3,5',7-0-β-D-triglucoside. The described monoglucoside is a new compound, isolated for the first time from plant material. The remaining three flavonoid constituents appear only in trace amounts characterized as heterosides of kaempferol, quercetin and myricetin with 0-glycoside bounded in the position 3
