摘要: 从鹅掌楸中分离得到了3个7-氧代阿朴菲型生物碱liridine (1),lysicamine (2)和liriodenine (3),采用MS、1D NMR和2D NMR等技术确定了化合物的结构,并利用2D NMR 技术对其核磁共振信号进行了全归属,纠正了文献中的归属错误.

Abstract: Aporphine alkaloids found in plants have good antihypertensive and antibacterial activities. In this study, three 7-oxo-aporphine alkaloids were isolated from Liriodendron Chinese and characterized by 1H and 13C NMR and 2D NMR techniques (including 1H-1H COSY, HSQC, HMBC and NOESY). The chemical shifts of the three compounds were assigned. Assignment mistakes found in the literature were corrected.

Key words: NMR, assignment, 2D NMR, 7-oxo-aporphine alkaloids, literature correction
