Pubescidin, an isoflavone glycoside from Centrosema pubescens

Abstract 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. © 1997 Elsevier Science Ltd. All rights reserved
