title: A bidesmosidic triterpene saponin from Cephalaria transsylvanica.
abstract: The structure of cephalaria saponin B, isolated from Cephalaria transsylvanica was elucidated as 3-O-([beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->2)-beta-D- xylopyranosyl]-[28-O-beta-D-glucopyranosyl])-3beta,23-dihydroxy-12(13)-oleanene-28-oic acid.
