ABSTRACT
Phytochemical investigation on Forsythia suspensa (Thunb.) Vahl afforded ten compounds, including five lignan glycosides and five phenylethanoid glycosides. The compounds were isolated by using HP-20 macroporous resin, silica gel, octadecyl silica gel (ODS), size exclusion chromatography resin HW-40 chromatography, and preparative HPLC. The structures were established through application of extensive spectroscopic methods, including ESI-MS, 1D-and 2D-NMR spectroscopy. They were identified as forsythialanside E (1), 8'-hydroxypinoresinol-4'-O-β-D-glucoside (2), 8'-hydroxypinoresinol (3), lariciresinol-4'-O-β-D-glucoside (4), lariciresinol-4-O-β-D-glucoside (5), forsythoside H (6), forsythoside I (7), forsythoside F (8), plantainoside B (9), and plantainoside A (10). Compound 1 was a new lignan glycoside.
