Abstract:
The iridoidic composition of Stachys glutinosa L. was examined in comparison with the results obtained in the phytochemical studies on S. corsica Pers. The presence of the known harpagide and acetyl-harpagide were showed together with that of a new di-glycosidic iridoid. The structure of this new compound, the 5-allosyloxy-aucubin, was demonstrated by comparison with the spectroscopical data of monomelittoside and of its 5-O-glucosyl-derivative, the melittoside. The presence of allose in Stachys genus seems to be a chemotaxonomical character.
