title: Triterpenoid saponins from Bellium bellidioides.
abstract: A new acylated triterpenoid saponin carrying the rare 2,3-branched glucose at C-28 of the aglycone bayogenin (2 beta, 3 beta, 23-trihydroxyolean-12-en-28-oic acid) was isolated from the whole plants of Bellium bellidioides. The structure was elucidated mainly by high field NMR experiments (1H and 13C NMR, HMBC, HMQC, COSY-45 at 600/150 MHz) as 3-O-beta-D-glucopyranosyl-28-O-[2-O-alpha-L-rhamnopyranosyl-3-O-beta-D- glucopyranosyl-6-O-acetyl-beta-D-glucopyranosyl]-23-O-acetylbayogenin . Additionally, three acylated derivatives of the known bellissaponin BS1 were obtained.
