Abstract: Eight compounds were isolated from Dichotomanthes tristaniaecarpa. Their structures were de-termined on the basis of chemical and spectral evidences as lupeol (1),betulin (2),5,7-dihydroxy-chromone (3),(-)-epicatechin(4), eriodictyol 3'-O-β-D-glucopyran-oside(5),eriodictyol 7-O-β-D-(6'-ethyl ester)-glucuronopyranoside (6),eriodictyol 7-O-β-D-(6'-methyl ester)-glucuronopyranoside (7),rosamultin (8), respectively.Among them, 6 and 7 were new compounds.
