Two new triterpenoid saponins from Adina pilulifera

Two new triterpenoid saponins, 3 g -O-g -D-xylopyranosyl (1 M 3)- f - l -rhamnopyranosyl-pyrocincholic acid 28-O-g -D-glucopyranosyl (1 M 6)-g -D-glucopyranosyl ester (1), and 3 g -O-g -D-xylopyranosyl(1 M 3)-f -L-rhamnopyranosyl-cincholic acid 28-O-g -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.
