Abstract:
From the whole plants and the roots of Gueldenstaedtia multiflora, which has been used in traditional Chinese medicine, five new oleanane glycosides and one lupane glycoside were isolated together with eight known oleanane glycosides and a medicarpin derivative. These structures were determined based on MS and 2D-NMR spectra.
