小木通木脂素成分研究

目的:研究小木通Clematis armandii Franch.的化学成分.方法:采用柱色谱进行分离纯化,通过理化方法和光谱分析鉴定化合物结构.结果:从小木通木质藤茎的乙醇提取物中分得9个木脂素成分,分别鉴定为armandiside(1),liriodendrin(2),(+)pinoresinol 4,4′-Ο-bis-β-D-glucopyranoside(3),(+)-pinoresinol 4′-Ο-β-D-glucopyranoside(4),(+)-syringa-resinol 4′-Ο-β-D-glucopyranoside(5),(+)-lariciresinol 4,4′-Ο-bis-β-D-glucopyranoside(6),(+)-lariciresinol 4-Ο-β-D-glucopyranoside(7),(+)-lariciresinol 4′-Ο-β-D-glucopyranoside(8),salvadoraside(9).结论:化合物1为新化合物,化合物2～9均为首次从该植物中分得.
