云木香乙醇提取物化学成分研究

目的:为了研究菊科风毛菊属植物云木香的化学成分。方法:采用硅胶柱色谱,SephadexLH-20,反相RP-18柱色谱等手段进行分离纯化,并通过波谱数据鉴定结构。结果:分离鉴定了17个化合物:ascleposideE(1),(+)-1-hydroxypinoresinol-4″-O-methylester-4'-β-D-glucopyranoside(2),(+)-1-hydroxy-pinoresinol-4″-O-β-D-glucopyranoside(3),(+)-1-hydroxypinoresinol-1-O-β-D-glucopyranoside(4),苯基-β-D-葡萄糖苷(phenyl-β-D-glucopyranoside,5),苄基-β-D-葡萄糖苷(benzyl-β-D-glucopyranoside,6),正丁基-β-D-葡萄糖苷(n-butyl-β-D-glucopyranoside,7),ilicicalcohol(8),β-cyclocostunolide(9),reynosin(10),11β,13-dihydroreynosin(11),arbusculinA(12),1β-hydroxy-arbusculinA(13),santamarin(14),脱氢木香内酯(dehydrocostuslactone,15),11β,13-dihydro-3-epizaluzaninC(16),木香烯内酯(costunolide,17)。结论:化合物1~2首次从该属植物中分离,化合物3,5~7为首次从该植物中分离。
