射干叶中黄酮碳苷的分离纯化与结构鉴定
Preparation and Structural Identification of C-glycoside Flavone Compounds Isolated from the Leaves of Belamcanda Chinensis
【摘要】 运用HP20型大孔吸附树脂、聚酰胺柱色谱、Sephadex-LH20型葡聚糖凝胶柱色谱和YMC制备型高效液相色谱柱(ODS)等色谱方法,从海南产射干叶中分离了4种黄酮碳苷.采用UV,1 H NMR,13 C NMR,MS等波谱学方法,结合熔点测定、盐酸-镁粉反应、三氯化铝显色反应等物理和化学方法,鉴定了它们的结构.4种黄酮碳苷分别为化合物Ⅰ:2″-O-鼠李糖基异牡荆素;化合物Ⅱ:2″-O-鼠李糖基当药素;化合物Ⅲ:异牡荆素;化合物Ⅳ:当药素.4种化合物均为首次从鸢尾科植物中分离.
【Abstract】 Using HP20macroporous resin,polyamide,Sephadex-LH20and YMC preparation column(ODS),four kinds of C-glycoside flavones were isolated from the leaves of Belamcanda chinensis grown in Hainan island.Combined with the measurement of melting points and chemical reactions,the structures of C-glycoside flavones were identified by analyzing the spectroscopic data of UV,1 H NMR,13C NMR,MS.They are compound Ⅰ 2″-O-rhamnosylisovitexin;compound Ⅱ 2″-O-rhamnosylswertisin;compound Ⅲ isovitexin and compoundⅣswertisin.All the compounds are isolated from the Iridaceae plants for the first time.
