The main saponins from the aerial parts and the roots of Solidago virgaurea subsp. 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).
