Cephalaria Saponin A, a New Bidesmosidic Triterpene Saponin from Cephalaria transsylvanica

A new bidesmosidic triterpene saponin, Cephalaria saponin A [2] was isolated from the MeOH extract of the flowers of Cephalaria transsylvanica. Its structure was determined as 3-O-([beta-D-glucopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->4)-beta-D -xylopyranosyl]-[28-O-beta-D-glucopyranosyl])-3 beta, 23-dihydroxy-12(13)-oleanen-28-oic acid.
