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 elucidate 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]-glycosides of 3-O-[beta-D-glucopyranosyl]polygalacic acid (5), and 3-O-[O-beta-D-glucopyranosyl-(1 --> 3)-beta-D-glucopyranosyl]-polygalacic acid (6).
