Isoflavone glycosides from Centrosema pubescens

Abstract Afromosin 7- O - β - d -apiofuranosyl- (1→2)- β - d -glucopyranoside, was isolated from the seeds of Centrosema pubescens , together with the known afromosin 7- O - β - d -glucopyranoside and irisolidone 7- O - β - d -glucopiranoside. Their structures were established by spectroscopic and chemical methods.
