Contribution à la phytochimie du genre Gentiana III. Etude des composés flavoniques et xanthoniques dans les feuilles de Gentiana lutea L. (2me communication)

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...
