  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.

  Nine flavonol oligosides of quercetin and kaempferol with glucose, xylose, and rhamnose as sugars were isolated from the seeds of Aesculus hippocastanum L (Hippocastanaceae). Five of them are new compounds (2 trisaccharides, 1 bisdesmoside, a nicotinic and a indolinone hydroxyacetic acid ester of the bisdesmoside). Their structures were elucidated mainly using 1H- and 13C-NMR techniques.

  In the course of a chemotaxonomic study of the genus Actinidia a new flavonol triglycoside, quercetin 3-O-β-D-[2G,-O-β-D-xylopyranosyl-6G-O-α-L-rhamnopyranosyl]glucopyranoside was identified amongst the 15 flavonols found in Actinidia arguta var. giraldii. This compound was characterized, along with quereetin 3-O-β-D-xylopyranosyl-(1-2)-O-β-D-glucopyranoside, by 1H and 13C NMR spectroscopy. The kaempferol analogues were also isolated.

  A study on the bioactive principles of Hedyotis diffusa Willd., led to the isolation of a new acyl flavonol di-glycoside which was characterized as kaempferol 3-O[2″-O-(E-6′′′-O-feruloyl)-β-D-glucopyranosyl]-β-D-galactopyranoside by spectral and chemical methods from the methanolic extract. In addition, three known flavonol glycosides and six known iridoid glycosides were also obtained. The above-mentioned glycosides were tested for antioxidant effects on xanthine oxidase inhibition, xanthine-xanthine oxidase cytochrome c and TBA-MDA systems.
