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
