概要
A new acidic triterpene glycoside, transsylvanoside A, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined to be 3-O-[beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1-->4)-al pha-L-rhamnopyranosyl(1-->4)-beta-D-xylopyranosyl]-3beta,23-dihydroxy delta(12)-oleanen-28-carboxylic acid.
