Seven known lignan glycosides were isolated from the leaves of Osmanthus heterophyllus: (+)-syringaresinol 4-O-beta-D-glucopyranoside, (+)-syringaresinol 4, 4'-O-di-beta-D-glucopyranoside, (+)-medioresinol 4, 4'-O-di-beta-D-glucopyranoside, (+)-medioresinol 4-O-beta-D-glucopyranoside,
A new lignan, (7R,7'R,8R,8'R)-8-hydroxypinoresinol 8-O-β-D-glucopyranoside 4'-methyl ether (7), was isolated from the flowers of Osmanthus fragrans var. aurantiacus along with six known lignans: (+)-phillygenin (1), phillyrin (2), (-)-phillygenin (3), (-)-epipinoresinol-β-D-glucoside (4),
