The new flavonol glycosides quercetin 3-O-β-(2-O-α-L-rhamnopyranosyl)-glucopyranoside uronic acid and kaempferol 3-O-β-(2-O-α-L-rhamnopyranosyl)-glucopyranoside uronic acid were isolated from the leaves of Alchemilla speciosa Buser together with 13 known flavonol and flavone glycosides and (+)-catechin. The structures were determined by spectroscopic methods.
