title: Two new sulfated oleanan saponins from Achyranthes root.
abstract: Two new sulfated oleanan saponins, sulfachyranthosides B (1) and D (2), were isolated from a water extract of Achyranthes root (root of Achyranthes bidentata). The structures were determined by analyses of spectroscopic data to be sulfates of achyranthosides B and D, respectively, at the 4'-position of the glucose moiety attached to the C-28 carboxylic acid of oleanolic acid.
