title: A new saponin from Deeringia amaranthoides.
abstract: A new triterpenoid saponin, 3-O-[alpha-L-rhamnopyranosyl (1----3)-beta-D-glucuronopyranosyl]-28-O-[beta-D-xylopyranosyl (1----2)-beta-D-glucopyranosyl]-3 beta-hydroxyolean-12-en-28-oate [3] has been isolated together with two known saponins, 3-O-[alpha-L-rhamnopyranosyl (1----3)-beta-D-glucuronopyranosyl]-3 beta- hydroxyolean-12-en-28-oic acid [1] and 3-O-[alpha-L-rhamnopyranosyl (1----3)-beta-D-glucuronopyranosyl]-28-O-[beta-D-glucopyranosyl]-3 beta- hydroxyolean-12-en-oate [2], from the fruits of Deeringia amaranthoides.
