Three new kaempferol glycosides, kaempferol 3‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→6)‐ β ‐ D ‐galactopyranosyl‐7‐ O ‐ α ‐ L ‐rhamnopyranoside ( 1 ), kaempferol 3‐ O‐β ‐ D ‐galactopyranosyl‐7‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→3)‐ α ‐ L ‐rhamnopyranoside ( 2 ), and kaempferol 3‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→6)‐ β ‐ D ‐galactopyranosyl‐7‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→3)‐ α ‐ L ‐rhamnopyranoside ( 3 ), were isolated from the whole herbs of Cardamine leucantha , along with three known kaempferol glycosides, kaempferol 7‐ O ‐ α ‐ L ‐rhamnopyranoside, kaempferitrin, and kaempferol 3‐ O ‐ β ‐ D ‐galactopyranosyl‐7‐ O ‐ α ‐ L ‐rhamnopyranoside. Their structures were elucidated on the basis of spectroscopic methods.
