Studies on Lignan Constituents of Clematis armandii Franch

AIM: To study the chemical const itue nts of Clematis armandii Franch.. METHOD: The constituen ts were isolated and purified by column chromatography and the structures were identified by physicochemical properties and spectral analysis. RESULT : Nine compounds were obtained as armandiside(1),liriodendri n(2) ,(+)-pinoresinol 4,4′-Ο-bis-β-D-glucopyranoside(3 ),(+)-pinor esinol 4′-Ο-β-D-glucopyranoside(4),(+)-syrin garesinol 4′-Ο-β -D-glucopyranoside(5),(+)-lariciresinol 4,4′-Ο -bis-β-D-gluco pyranoside(6),(+)-lariciresinol 4-Ο-β-D-gluc opyranoside(7),(+)-lariciresinol 4′-Ο-β-D-glucopyranoside( 8),and salvadoraside(9). CONCLUSION: All the se compounds were ob tained from this plant for the first time,and compound 1 is a new g lucoside.
