Five isoflavonoid glycosides together with the corresponding aglycones
have been isolated from the n-BuOH-soluble fraction of a methanol ext
ract of the roots of Eriosema tuberosum. One compound is new and its s
tructure has been established by spectroscopic analyses and chemical m
ethods as 5-O-methylgenistein -D-apiofuranosyl-(1-->6)-O-beta-D-glucop
yranoside. (C) 1998 Elsevier Science Ltd. All rights reserved.
