概要
Transsylvanoside B, which is a new acidic triterpene glycoside, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined as 3-O-[beta-D- glucopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyran osy l (1-->4)-beta-D-xylopyranosyl]-3 beta,23-dihydroxy delta 12-oleanen-28-carboxylic acid.
