Medicago lupulina
(NCBI TaxID 47085,
species name lookup)
Taxonomic group: plant / Streptophyta
(Phylum: Streptophyta)
Organ / tissue: flower
The structure was elucidated in this paperPublication DOI: 10.5586/asbp.1988.054Journal NLM ID: 101235501Publisher: Warszawa, Państwowe Wydawn. Nauk. [etc.]
Institutions: Department of Biochemistry and Physiology of Crop Plants, Institute of Soil Science and Plant Cultivation, Pulawy, Poland
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.
