The Main Saponins from the Aerial Parts and the Roots ofSolidago virgaureasubsp.virgaurea*

Two new (3, 4) and two known (1, 2) genuine acylated bisdesmosidic triterpenoid glycosides of polygalacic acid (2 beta, 3 beta, 16 alpha, 23-tetrahydroxyolean-12-en-28-oic acid) were isolated from the aerial parts, as well as from the roots, of Solidago virgaurea L. subsp. virgaurea. The structures of these esters were elucidated as 4-O-fucopyranosyl-acylated compounds (1, 2, 3, 4) of 28-[O-alpha-L-rhamnopyranosyl-(1-->3)-O-beta-D-xylopyranosyl- (1-->4)-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-fucopyranosyl]-glycosid es of 3-O-[beta-D-glucopyranosyl]-polygalacic acid (5), and 3-O-[O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl]- polygalacic acid (6).
