Abstract:
A new monoterpene glycoside, shionoside C, and a new oleanane-type triterpene glycoside, aster saponin G, were isolated from the roots of Aster tataricus. Their structures were elucidated on the basis of spectral and chemical methods. Shionoside C is L-endo-camphanol-8-3,5-isopropylidene-beta-D- apiofuranosyl-(1-6)-beta-D-glucopyranoside, aster saponin G is 3-O-[O-alpha-L-arabinopyranosyl-(1-6)-beta-D-glucopyranosyl]-2 beta, 3 beta, 16 alpha-trihydroxyolean-12-en-28-oic acid (asterogenic acid) 28-[O-beta-D-xylopyranosyl-(1-4)-alpha-L- rhamnopyranosyl-(1-2)-beta-D-xylopyranosyl]ester.
