Description
Nine flavones and adenosine have been identified in aerial parts of alfalfa, and their structures were established by spectral (FABMS and NMR) techniques. Five of the identified compounds, including apigenin 7-O-[β-d-glucuronopyranosyl(1→2)-O-β-d-glucuronopyranosyl]-4‘-O-β-d-glucuronopyranoside, apigenin 7-O-[2-O-feruloyl-β-d-glucuronopyranosyl(1→2)-O-β-d-glucuronopyranosyl]-4‘-O-β-d-glucuronopyranoside, apigenin 7-O-{2-O-feruloyl-[β-d-glucuronopyranosyl(1→3)]-O-β-d-glucuronopyranosyl(1→2)-O-β-d-glucuronopyranoside}, apigenin 7-O-{2-O-p-coumaroyl-[β-d-glucuronopyranosyl(1→3)]-O-β-d-glucuronopyranosyl(1→2)-O-β-d-glucuronopyranoside}, and luteolin 7-O-[2-O-feruloyl-β-d-glucuronopyranosyl(1→2)-O-β-d-glucuronopyranosyl]-4‘-O-β-d-glucuronopyranoside, have not been reported before in the plant kingdom. Additionally, five known compounds, including apigenin 7-O-β-d …
