Three new flavonoids (1-3) and 11 known compounds (genistein, isoprunetin, wighteone, laburnetin, alpinumisoflavone, genistin, genistein 8-C-glucoside, apigenin, isokaempferide, licoflavone C, and D-pinitol) were isolated from the aerial parts of Genista ephedroides. The structures of the new compounds were established as hydroxyalpinumisoflavone (1) [4',5-dihydroxy-2 "-methyl-2 "-hydroxymethylpyrano(5 ",6 ": 6,7)isoflavone], ephedroidin (2) [4',5,7-trihydroxy-8-(2-hydroxy-3-methyl-3-butenyl)flavone], and genisteone (3) (7-O-glucosylwighteone) by means of spectroscopic methods.

Abstract
Three new flavonoids (1-3) and 11 known compounds (genistein, isoprunetin, wighteone, laburnetin, alpinumisoflavone, genistin, genistein 8-C-glucoside, apigenin, isokaempferide, licoflavone C, and D-pinitol) were isolated from the aerial parts of Genista ephedroides. The structures of the new compounds were established as hydroxyalpinumisoflavone (1) [4',5-dihydroxy-2 "-methyl-2 "-hydroxymethylpyrano(5 ",6 ": 6,7)isoflavone], ephedroidin (2) [4',5,7-trihydroxy-8-(2-hydroxy-3-methyl-3-butenyl)flavone], and genisteone (3) (7-O-glucosylwighteone) by means of spectroscopic methods.File in questo prodotto:
