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 chinensis Bge . 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.
