title: Two new triterpenoid saponiins from Adina pilulifera.
abstract: Two new triterpenoid saponins, 3beta-O-beta-D-xylopyranosyl (1 --> 3)-alpha-L-rhamnopyranosyl-pyrocincholic acid 28-O-beta-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranosyl ester (1), and 3beta-O-beta-D-xylopyranosyl(l --> 3)-alpha-L-rhamnopyranosyl-cincholic acid 28-O-beta-D-glucopyranosyl ester (2) were isolated from the roots of Adina pilulifera, together with 18 known compounds. The structures of 1 and 2 were determined by spectroscopic methods.
