Abstract—Two new triterpenoid saponins were isolated from the alcoholic extract of roots of Aster auriculatus. Their structures have been determined on the basis of spectral and chemical evidence as 3-0-P-D-glucuronyl-16a-hydroxyolean-12-en-28-oic acid-28-O-a-L-arabino-pyranosyl(l -4)-a-L-rhamnopyranosyl( 1 -2)-3-D-xylopyranosyl-( 1 -3)-P-D-xylopyranosyl( 1 -3)-a-L-arabinopyranoside and methyl ester of 3-0-P-D-glucuronyl-16a-hydroxyolean-12-en 28-oic acid-28-0-P-D-xylopyranosyl( 1 -3)-a-L-arabinopyranosyl( 1 -4)-p-D-apiofiiranosyl( 1 -3)-a-L-rhamnopyranosvK 1 -2)-P-D-xvlopyranoside. ...
