title: Two new glucuronide saponins, Achyranthosides G and H, from Achyranthes fauriei root.
abstract: Two oleanolic acid saponins named achyranthosides G (1) and H (2) were newly isolated from Achyranthes fauriei root as methyl esters in addition to methyl esters of achyranthosides A - F and five oleanolic acid glucuronides (chikusetsusaponins IVa, V, 28-deglucosyl chikusetsusaponin V, pseudoginsenoside RT(1), and oleanolic acid 3-O-beta-D-glucuronopyranoside) as well as oleanolic acid 28-O-beta-D-glucopyranoside, beta-ecdysterone, and polypodine B. Their structures were characterized as follows on the basis of the chemical and spectroscopic evidences.
