- Abstract
- Three new flavonol glycosides (1-3) and three known lignan amides (4-6) were isolated from the MeOH extract of the aerial parts of Tetragonia tetragonoides. The chemical structures of the new compounds (1-3) were determined to be 6-methoxykaemferol-3-O-beta-D-glucosyl (1"'-> 2")-beta-D-glucopyranosyl-(6""-(E)-caffeoyl)-7-O-beta-D-glucopyranoside (1), 6,4'-dimethoxy kaemferol-3-O-beta-D-glucosyl (1"'-> 2")-beta-D-glueopyranosyl-(6""-(E)-caffeoyl)-7-O-beta-D-glucopyranoside (2), 4'-methoxypatuletin-3-O-beta-D-glucosyl (1"'-> 2") -beta-D-glucopyranosyl-(6""-(E)-caffeoyl)-7-O-beta-D-glucopyranoside (3) on the basis of extensive spectroscopic analyses (FAB-MS/MS, 1D and 2D NMR experiments).
