摘要: 从华北产对叶百部(Stemona tuberosa Tour)根部分离出两种生物碱,对叶百部烯酮1(tuberostemoenone)和对叶百部酮2(tuberostemonone),其中化合物1的结构未见报道.应用2D NMR梯度反相实验,GCOSY、GNOESY、GHMQC和GHMBC对其化学结构进行了深入研究,归属了其1H、13C NMR化学位移.计算机分子模拟与NMR研究取得一致结论.

关键词: 对叶百部烯酮, 对叶百部酮, 二维核磁共振, 梯度场

Abstract: The Tuberostemoenone 1 and Tuberostemonone 2 were isolated from the roots of Stemona tuberosa Tour of the north part of China.In this paper, the 2D NMR gradient inverse techniques(GCOSY, GNOESY, GHM QC and GHMBC)were successfully applied to determine the structures of compounds 1 and 2.Tuberostemoenone 1 is a new alkaloid with novel skeletone.All of the 1H and 13C NMR chemical shifts of compounds 1, 2 were assigned by 2D NMR, and their relative configurations were discussed.The structures of compounds 1, 2 were simulated by computer molecular modelling, their results were the same as 2D NMR.

Key words: Tuberostemoenone, Tuberostemono ne, 2D NMR, Gradient field
