Four new tetrahydrofuranoid lignan glycosides (7S,8R 7'R,8 S)-4,9 4,7 tetrahydroxy-3 3 dimethoxy 79-epoxylignan 9 O-beta-D-glucopyranoside (2) (7R,8S,7 S 8 R)-4,9,4 7 -tetrahydroxy-3,3 -dimethoxy-7,9 -epoxylignan 9 O-beta D-glucopyranoside (3) (7 R,8S,7'R,8 S)-4,9,4 9 tetrahydroxy 3,3'-dimethoxy-7,7 epoxylignan 9-O beta D-glucopyranoside (4), and rel (7R,8S,7'S,8 R)-4 9,4,9' tetrahydroxy-3,3' dimethoxy-77'-epoxylignan 9-O beta D-glucopyranoside (5) and ten known lignan glycosides I and 6 14, were isolated from the leaves of Osmanthas fragrans LOUR var aurantiacus MAKINO Their structures were established on the basis of spectral and chemical studies.
