A phytochemical study of a Venezuelan species Hydrocotyle multifida led to the isolation of five oleanane-type glycosides: two previously undescribed and three known ones. Their structures were established by 2D NMR spectroscopic techniques and mass spectrometry as 3-O--D-galactopyranosyl-(12)-[-Larabinopyranosyl-(13)]--D-glucuronopyranosyloleanolic acid and 3-O--D-glucopyranosyl-(12)--D-glucopyranosyl-(12)--D-glucuronopyranosyloleanolic acid. These results represent a significative contribution to the chemotaxonomy of the Hydrocotyle genus.
