Abstract :From the aerial parts of Galium verum subsp. verum L. were isolated 7 iridoid glycosides, asperuloside insert ignore into journalissuearticles values(1);, asperulosidic acid insert ignore into journalissuearticles values(2);, deacetyl-asperulosidic acid insert ignore into journalissuearticles values(3);, monotropein insert ignore into journalissuearticles values(4);, 6-O-epi-acetylscandoside insert ignore into journalissuearticles values(5);, daphylloside insert ignore into journalissuearticles values(6); and deacetyl-daphylloside insert ignore into journalissuearticles values(7);; 2 flavonol glycosides, astragalin [= kaempferol 3-O-b-glucopyranoside] insert ignore into journalissuearticles values(8); and rutin [= quercetin 3-O- rutinoside] insert ignore into journalissuearticles values(9);; and 2 monoterpene glycosides, betulalbuside A insert ignore into journalissuearticles values(10); and insert ignore into journalissuearticles values(2E);-2,6-dimethyl-2,7-octadien-1,6-diol-6-O-b -glucopyranoside insert ignore into journalissuearticles values(11);. The structures of the isolates were established by 1D and 2D NMR spectroscopy in combination with IR, UV and ESI-MS analysis.
