To identify the volatiles of Platycodon roots, the three-year-old and the 24-year-old Platycodon roots cultivated in a local farm were extracted with ethyl ether by SDE method. 54.71㎎% and 80.01㎎% of volatile components were collected in the three-year-old and in 24-year-old Platycodon roots, respectively. As a result of GC/MS(TIC) analysis, 24 and 28 compounds were identified, respectively. The amounts of volatile components such as hexanol, trans-2-hexenol and nonanal in 24-year-old roots were detected above ten times than those in 3-year-old roots. The Volatiles of 24-year-old roots were fractionated by SCC and identified by GC/MS to be 10 hydrocarbons, 8 alcohols, 10 aldehydes, 5 esters, 6 acids and 1 unknown compound as the major components. The species and total amounts of volatile component in 24-year-old Platycodon roots were considered to be higher than those in 3-year-old Platycodon roots. * Abbreviations 1.
