Triterpenoid saponins from Bellis sylvestris, I. Structures of the major deacylsaponins.
Two major saponins from Bellis sylvestris have been isolated and their structures determined, mainly by high-field nmr spectroscopy. One of these [2] was identical with bellissaponin BS1 from Bellis perennis, while the second is a new triterpenoid saponin [1], named besysaponin C12, and identified as 3-O-alpha-L-rhamnopyranosyl-2 beta,3 beta,16 alpha,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->2)-beta-D- fucopyranoside.
