摘要:

从中药黄独Dioscorea bulbifera L.中通过柱层析色谱分离得到3个化合物,其中1 个为新骨架的呋喃二萜类化合物命名为neodiosbulbin, 采用核磁共振(1H, 13C, DEPT, 1H-1H COSY, HMQC, HMBC, NOESY and TOCSY )的波谱方法确定了它 的结构和相对构型,其余的2个化合物分别为Diosbulbin B, 5-ureidohydautotion.

关键词: 黄独, 呋喃二萜

Abstract:

This Paper Reported the structure elucidation of three compounds, Neodiosbulbin  (1), Diosbulbin B (2) and 5-ureidohydautotion (3) isolated from Dioscorea bulbi fera L. On the basis of spectroscopic evidences, mainly modern 2D NMR techniqu e, their structures were determined. Neodiosbulbin (1) is a new fura nditerpenoid  compound, Diosbulbin B (2)  and 5-ureidohydautotion are  known fur anditerpenoid compounds.

Key words: dioscorea bulbifera L, furanditerpenoid
