Abstract Five isoflavonoid glycosides together with the corresponding aglycones have been isolated from the n-BuOH-soluble fraction of a methanol extract of the roots of Eriosema tuberosum. One compound is new and its structure has been established by spectroscopic analyses and chemical methods as 5-O-methylgenistein 7-O-β- d -apiofuranosyl-(1 → 6)-O-β- d -glucopyranoside.
