Taxonomic relationships between some inulin containing plants such as Platycodon and Codonopsis have been investigated comparing their contents of inulin crystals, resin, as well as TLC patterns of saponins and acetylenes. Although Platycodon and Codonopsis have been known to be close in anatomic characters, the present results showed that there were significant differences between not only in the genus but also in the species.
