From the leaves of Bencomia caudata and Dendriopoterium menendezii a new triterpenoid glycoside has been isolated. Its structure was determined as 3-O-galloyl-23-hydroxytormentic acid 28-O-beta-D-glucopyranoside mainly from the NMR spectra. In addition, several known triterpenoids have been isolated from six other species of the Sanguisorbeae. A comparative study of the triterpene occurrence pattern has been performed.
