A new flavonol glycoside from the aerial parts of Astragalus vulneraria
Chemical and Pharmaceutical Bulletin 48(12) (2000)
1994-1995
A new flavonol glycoside, isorhamnetin 3-O-β-D-apiofuranosyl-(1→2)-α-L-rhamnopyranosyl-(1→6)]-β-D-galactopyranoside, and the known diglycoside, isorhamnetin 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside were isolated from the aerial parts of Astragalus vulneraria. Characterization of the two compounds was done by spectroscopic methods (1D and 2D NMR, and FAB-MS).
