摘　　要：目的:研究傣药奶子藤根的化学成分。方法:采用甲醇对奶子藤根的粗粉进行浸渍和回流提取,利用硅胶、反相硅胶、制备薄层色谱、半制备高效液色谱等多种柱色谱法对奶子藤根中的生物碱类成分进行分离纯化,通过NMR和ESI-MS等波谱技术以及与文献报道数据比对,鉴定化合物结构。结果:从奶子藤根中分离得到9个化合物,分别鉴定为:狗牙花碱(1)、非洲伏康树碱(2)、 7-羟基吲哚海尼山辣椒碱(3)、6-酮基伊菠加因(4)、14,15-环氧-氮-甲基白坚木胺(5)、14,15-二羟基-氮-甲基白坚木胺(6)、伊波叶黄素(7)、喜树次碱(8)、lirofolines A(9)。结论:以上化合物均为首次从奶子藤属植物中分离得到。Objective:To study alkaloids from the root of Bousigonia mekongensis.Methods:The coarse powder of the root from Bousigonia mekongensis was impregnated and reflux extracted by methanol.The alkaloids were isolated and purified by using various chromatographic techniques,including silica gel,ODS,pre-TLC and HPLC.Their structures were elucidated by NMR and ESI-MS spectroscopy and compared with the reported data.Results:Nine alkaloids were isolated and identified as coronaridine(1),voacristine(2),heyneanine hydroxyindolenine(3),6-oxoibogaine(4),N-methylvoaphylline(5),voafinidine aspidosamine(6),iboluteine(7),venoterpine(8),lirofolines A(9),respectively.Conclusion:All compounds are isolated from the Bousigonia genus for the first time.
