【摘要】 目的:研究海南狭瓣鹰爪花茎的生物碱成分。方法:生药用70%乙醇提取,提取物酸水溶解,酸水液氨水碱化后氯仿萃取,氯仿部位用硅胶柱色谱等色谱方法分离纯化,NMR等波谱法进行结构鉴定。结果:分离得到了8个生物碱类化合物,结构鉴定为spinosine(1),3-hydroxynornuciferine(2),juzirine(3),artabotrine(4),liridine(5),assim-ilobine(6),isococlaurine(7),-Ndemethylarmepavine(8)。结论:上述化合物均为首次从该植物中分得,化合物1,3,7,8为首次从该属植物分得。更多还原

【Abstract】 Objective: To investigate the alkaloids from the stem of Artabotrys hainanensis.Method: Compounds in plant extracts were separated by silica gel and sephadex LH-20 column chromatography.Chemical structures were elucidated by chemical and spectral analyses including UV,（）¹H-NMR,（）¹³C-NMR,ESIMS and ESI-MS-MS.Result: Eight alkaloids were isolated and identified as spinosine（1）,3-hydroxynornuciferine（2）,juzirine（3）,artabotrine（4）,liridine（5）, assimilobine（6）,isococlaurine（7）,N-demethylarmepavine（8）.Conclusion: All alkaloids were isolated from this plant for the first time and compounds 1,3,7 and 8 were isolated from genus Artabotrys for the first time.更多还原
