title: Characterization and antiglycation activity of phenolic constituents from Viscum album (European Mistletoe).
abstract: 4'-O-[beta-D-Apiosyl(1-->2)]-beta-D-glucosyl]-5-hydroxyl-7-O-sinapylflavanone (1), 3-(4-acetoxy-3,5-dimethoxy)-phenyl-2E-propenyl-beta-D-glucopyranoside (2), 3-(4-hydroxy-3,5-dimethoxy)-phenyl-2E-propenyl-beta-D-glucopyranoside (3), 5,7-dimethoxy-4'-O-beta-D-glucopyranoside flavanone (4), 4',5-dimethoxy-7-hydroxy flavanone (5), and 5,7-dimethoxy-4'-hydroxy flavanone (6), were isolated from the organic extracts of Viscum album L. (European Mistletoe). These compounds were studied for their anti-glycation and antioxidant properties. The structures of new compounds 1 and 2 were deduced on the basis of spectroscopic evidence.
