目的:对多裂骆驼蓬地上部分的化学成分进行研究。方法:应用多种色谱技术进行分离纯化,通过理化方法和波谱数据进行结构鉴定。结果:分离并鉴定了6个生物碱类成分,分别为:脱氧鸭嘴花酮碱(1)、l-鸭嘴花酮碱(2)、哈尔明碱(3)、鸭嘴花种碱(4)、吴茱萸碱(5)和fagomine(6)。结论:其中,化合物5和6为首次从该属植物中分离得到。 Objective: To study the chemical constituents of Peganum multisectum. Methods: A variety of chromatographic techniques were used for the isolation and purification. The structures were identified by physicochemical methods and spectral data. Results: Six alkaloids were isolated and identified as follows: deoxybenazidone (1), l-nadeponin (2), haeminemine (3) (4), evodiamine (5) and fagomine (6). Conclusion: Among them, compounds 5 and 6 were isolated from this genus for the first time.
