Abstract
The xanthone isogentisin and two flavonic heterosides (isocrientin‐4′‐O‐glucoside and isovitexin‐4′‐O‐glucoside) have been isolated from leaves of Gentiana lutea L. by means of column chromatography on polyamide. The determination of the structures and the NMR. spectra of the acetylated derivatives are reported.
