Abstract

The conversion of euphorianin to deacetyldehydroeuphorianin which was used in an X-ray crystal structure analysis is described. A new pentacyclic structure related to ingol tetraacetate is described for euphorianin.

Keywords: Deacetyldehydroeuphorianin; Euphorbia poisonii; Euphorbiaceae; Macrocyclic Diterpene; Structure of Euphorianin
