Saponins from Roots of Platycodon grandiflorum. Part 1. Structure of Prosapogenins
Seven new prosapogenins have been isolated as their methyl esters from the roots of Platycodon grandiflorum A.DC., along with the known 3-O-β-D-glucopyranosylplatycodigenin methyl ester (3).The structures of the seven compounds were elucidated using 13C and 1H n.m.r. spectroscopy.
