| A NEW TRITERPENE GLYCOSIDE FROM THE ROOT OF ASTER TATARICUS L. F | |
| 摘 要： | A new oleanane-rype triterpene glycoside, Aster saponin G, was isolated from the root of Aster tataricus L.F. (Compositae). and its structure was elucidated on the basis of spectral and chemical methods. Aster saponin G is 3-0α-L-arabinopyranosyl-(1→6)-β-D-glucopyranosyl]-2β,3β, 16α-trihydroxyolean-12-en-28-oic acid(asterogenic acid) 28-0-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl] ester |
