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 mg% and 891.6 mg% 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.

도라지는 약리성분을 많이 함유하고 있으며 식품 및 생약재료로 널리 사용되고 있다. 재배도라지 24년근 및 3년근의 주요성분을 동정하기 위하여 약리성분 분석에 우선하여 일반성분을 분석하고 그것을 기초자료로 사용하였다. 재배도라지의 일반성분, 무기물과 지방산의 조성비는 24년근과 3년근 간에서 별 차이가 없었다. 재배도라지의 총 아미노산 함량은 24년근과 3년근에서 각각 375.8 mg%, 891.6 mg%였다. 재배도라지의 아미노산 종류는 24년근과 3년근 양쪽에서 cysteine를 제외한 총 16종의 아미노산을 자동아미노산 분석기로 확인하였다. 재배도라지의 지방산함량이 가장 높은 것은 24년근과 3년근 양쪽 모두에서 linoleic acid였고 그 함량은 24년근 및 3년근에서 48.7%, 39.1%였다.
