Abstract
|
|
|
|
Platycodon root contains abundant pharmaceutical substances and is widely used as a food and a medicinal herb. To identify the major components of the three-year-old and the 24-year-old platycodon roots cultivated in a local farm were analyzed and compared with their chemical compositions prior to their pharmaceutical substances, which were used as the fundamental data. There were no differences in chemical composition, inorganic compositions and fatty acid compositions between the 24-year-old and three-year-old roots. Total amino acid contents were 375.8 ㎎% and 891.6 ㎎% in the 24-year-old and three-year-old platycodcon roots, respectively. Sixteen species of amino acid were identified by amino acid autolyzer except cysteine both in the 24-year-old and three-year-old roots. Linoleic acid, which was the highest fatty acid contained both in the 24-year-old and three-year-old roots, was estimated to be 48.7% and 39.1% of total fatty acids, respectively.
