摘要：
Two previously undescribed triterpenoid saponins together with 4 known ones were isolated from the stem bark of Pentaclethra eetveldeana De Wild. & Th. Dur. Their structures were elucidated by spectroscopic methods including 1D and 2D NMR experiments in combination with mass spectrometry as 3-O-beta-D-glucopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 3)]-beta-D-glucopyranosyl-(1 -> 4)-beta-D-glucopyranosyl-(1 -> 3)-alpha-L-rhamnopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 4)]-alpha-L-arabinopyranosyloleanolic acid and 3-O-beta-D-glucopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 3)]-beta-D-glucopyranosyl-(1 -> 4)-beta-D-glucopyranosyl-(1 -> 3)-alpha-L-rhamnopyranosyl-(1 -> 2)-[beta-D-glucopyranosyl-(1 -> 4)]-alpha-L-arabinopyranosylhederagenin.
