Article abstract of DOI:10.1016/S0031-9422(97)00097-6

A new isoflavone glycoside, irisolidone 7-O-β-D-apiofuranosyl-(1 → 2)- β-D-glucopyranoside was isolated from the seeds of Centrosema pubescens along with sitosterol, stigmasterol and sitosterol 3-O-β-D-glucopyranoside. The structures of new and known compounds were established by spectroscopic and chemical methods.
