Abstract
|
|
|
|
Platycodon root contains abundant pharmaceutical substances and is widely used as a food and a medicinal herb. The three-year-old and the 24-year-old Platycodon roots cultivated in a local farm were analyzed and compared with their pharmaceutical substances to identify the major components. Reverse column HPLC analysis of ethanol extracts from the 24-year-old roots showed some distintive peaks after the retention time of 50 min which were absent in the extracts from the three-year-old roots. This indicates that several pharmaceutical substances are present in the older roots. There were no differences in sterol composition and saponin content between the 24-year and three-year-old roots. The 15-year-old and the 23-year-old Platycodon roots, the 6-year-old Ginseng root, and the three-year-old Condonopsis root all did not show significant anticomplement activity.
