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 RT1, and oleanolic acid 3-O-β-d-glucuronopyranoside) as well as oleanolic acid 28-O-β-d-glucopyranoside, β-ecdysterone, and polypodine B. Their structures were characterized as follows on the basis of the chemical and spectroscopic evidences.
