Iridoids,Flavonoids and Monoterpene Glycosides from Galium verum subsp.verum

摘要

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