- Abstract
Four new flavonoid glycosides, 3-O-[α-L-arabinopyranosyl-(1→2)-β-D-galactopyranosyl]-7-O-β-D-glucopyranosylkaempferol (1), 3-O-(α-L-arabinopyranosyl-(1→2)-{4-O-[(E)-caffeoyl]-β-D-galactopyranosyl})-7-O-β-D-glucopyranosylquercetin (2), 3-O-{2-O-[(E)-caffeoyl]-α-L-arabinopyranosyl-(1→2)-β-D-galactopyranosyl}-7-O-β-D-glucopyranosylkaemperfol (3), and 3-O-{2-O-[(E)-caffeoyl]-α-L-arabinopyranosyl-(1→2)-β-D-galactopyranosyl}kaempferol (4), together with two known compounds were isolated from the aerial parts of Ranunculus chinensisBge. The structures of the new glycosides were determined on the basis of spectroscopic analysis, including 1D- and 2D-NMR, and ESI-MS techniques, and chemical methods.
