A New Lathyrane Diterpenoid Ester from Euphorbia Dracunculoides.

A new lathyrane diterpenoid ester, euphordracunculin C ( 1), together with a phenolic amide, 4-hydroxy-N-[3-(4-hydroxy-3-methoxyphenyl)-1-oxo-2-propen-1-yl]-3-methoxybenzamide ( 2), was isolated from the aerial parts of Euphorbia dracunculoides. The structure of the new compound was elucidated on the basis of spectroscopic analysis including 1D and 2D NMR techniques. [ABSTRACT FROM AUTHOR]
