Two chalcone glycosides were isolated, together with seven known flavonol glycosides, from the leaves of Asarum canadense. The structures of the chalcone glycosides were established as chalcononaringenin 2',4'-di-O-glucoside and chalcononaringenin 2'-O-glucoside-4'-O-gentiobioside by chemical, UV, FAB MS, 1H and 13C NMR evidence.
Aristolochiaceae, Asarum canadense, chalcononaringenin 2', 4'-di-O-glucoside, chalcononaringenin 2'-O-glucoside-4'-O-gentiobioside
