Abstract
Three new triterpenoid saponins, 1-3, were isolated from the roots of Acant hophyllum squarrosum. Their structures were established mainly by 2D NMR te chniques as 3-O-beta -D-galactopyranosyl-(1-->2)-[beta -D-xylopyranosyl-(1- ->3)]-beta -D-glucuronopyranosyl-gypsogenin-28-0-,8-D-xylopyranosyl-(1-->3) -beta -D-xylopyrano- syl-(1-->4)-beta -D-xylopyranosyl-(1-->4)-3-O-acetyl-a lpha -L-rhamnopyranosyl-(1-->2)-3,4-di-O-acetyl-beta -D-fucopyranoside (1), 3-O-beta -D-galactopyranosyl-(1-->2)-[beta -D-xylopyranosyl-(1-->3)]-beta -D-glucuronopyranosyl-gypsogenin-28-O-beta -D-xylopyranosyl-(1-->4)-alpha - L-rhamnopyranosyl-(1-->2)-[5-O-acetyl-alpha -L-arabinofuranosyl-(1-->3)]-4- O- acetyl-beta -D-fucopyranoside (2), and 3-O-beta -D-glucopyranosyl-quilla ic acid-28-O-alpha -L-rhamnopyranosyl-(1-->2)-alpha -L-arabinopyranosyl-(1- ->2)-beta -D-glucopyranosyl-(1-->6)]-beta -D-glucopyranoside (3).
