title: A new triterpenoid saponin from Isolatocereus dumortieri.
abstract: A new triterpenoid saponin, named dumortierinoside A, was isolated from Isolatocereus dumortieri. The structure was determined as dumortierigenin 3-O-alpha-L-rhamnopyranosyl (1-->2)-beta-D-glucopyranosyl(1-->2)-beta-D-glucuronopyranoside (1) on the basis of NMR and mass spectroscopy.
