Resumo

Erythrocentaurin was isolated from two gentianaceous plants—viz., Enicostemma hyssopifolium (Willd.) Verd. (synonymous with E. littorale) and Swertia lawii Burkill., as a native compound. Its natural occurrence was demonstrated for the first time by using a modified isolation procedure. The identity of the compound was established by chemical transformations and spectral (UV, IR, NMR, and mass spectra) evidence. Phylogenetic significance of the cooccurrence of erythrocentaurin and a number of structurally related monoterpene alkaloids in E. hyssopifolium is discussed.
