Abstract
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.This publication has 1 reference indexed in Scilit:
