Abstract

The chemical study of the leaves and twigs of Viscum album led to the isolation of five new lignan glycosides, namely, ligalbumosides A-E (2-6) and one known lignan glycoside, alangilignoside C (1). The structures of five new lignan glycosides were determined to be (7R,8S,8'S)-4,9,4'-trihydroxy-3,5,3',5'- tetramethoxy-7,9'-epoxylignan 9-O-β-D-glucopyranoside (2), (7S,8S,7'S,8'R)-4,9,4'-trihydroxy-3,5,3',5',7'-pentamethoxy-7,9'-epoxylignan 9-O-β-D-glucopyranoside (3), (7R,8R,7'S,8'S)-4,9,4'-trihydroxy-3,5,3',5', 7'-pentamethoxy-7,9'-epoxylignan 9-O-β-D-glucopyranoside (4), (7S,8R,7'S,8'R)-4,9,4'-trihydroxy-3,5,3',5',7'-pentamethoxy-7,9'-epoxylignan 9-O-β-D-glucopyranoside (5), and (7R,8S,7'R,8'S)-4,9,4',7'-tetrahydroxy-3, 5,3',5'-tetramethoxy-7,9'-epoxylignan 9-O-β-D-glucopyranoside (6) using 1D-, 2D-NMR, and CD spectra, chemical methods, as well as comparing the results with those reported in the literature.
