Abstract

Chemical composition of dried roots of wild and cultivated Codonopsis lanceolata has been investigated. General composition was similar in both Codonopsis lanceolata. Free sugars from the root were fructose, glucose and sucrose. The contents of the sugars were higher in the cultivated than in the wild. Maltose was detected only in the cultivated and its level was 0.05%.. Free amino acids were consisted of 16 amino acids: lysine, histidine, arginine aspartic acid, threonine, serine, glutamic acid. proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine and phenylalanine. No significant difference in the contents was found between the wild root and the cultivated. Free fatty acids were palmitate, linoleate and linolenate, and the contents of those acids were higher in the cultivated root than in the wild. The contents of crude saponin were 1.5% in the wild root and 1.4% in the cultivated, respectively.

수분함량 약 10%로 건조된 야생더덕과 경작더덕의 화학적 성분을 조사한 결과 야생더덕과 경작더덕의 일반 성분은 가용성 물질이 각각 12.9%, 10.7%, 조단백질이 각각 18.8%, 17.1%, nitrogen free extract가 각각 30.3% 33.8%로써 야생더덕과 경작더덕 간의 특징적인 차이는 없었다. 유리당의 조성은 fructose, glucose, sucrose였으며 그 함량은 야생에 비하여 경작의 경우가 높았고 maltose의 경우 야생더덕은 나타나지 않았으나 경작더덕은 0.05%로 나타났다. 유리 아미노산은 lysine, histidine, arginine, aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine등 16종이 나타났으며 야생더덕과 경작더덕 사이에 함량의 차이는 다소 있었으나 그 외 별다른 차이는 발견되지 않았다. 유리 지방산의 조성은 palmitate, linoleate, linolenate가 검출되었으며 야생더덕보다 경작더덕의 함량이 높았다. crude saponin의 함량은 야생더덕과 경작더덕이 각각 1. 5%, 1.4%였다.
