Seventeen new saponins (2)-(18) have been isolated from the roots of Platycodon grandiflorum A.DC. and their structures determined by comparison of their 13C n.m.r. signals with those of known prosapogenins (19)-(26) and of the sugar chain at C-28 in platycodin-D (1).Eight of these saponins were found to have an O-acetyl group which migrated both readily and reversibly between the 2-O- and 3-O-positions of the rhamnose moiety in their sugar chain.
