Abstract
Proximate compositions, minerals and protein fractions of the roots of cultured and wild Codonopsis lanceolata of different age groups were examined as the basic research for the study of their source of processed foods. The most abundant proximate composition of the roots of C. lanceolata was observed to be total sugars and next come crude protein, crude fiber, crude fat and ash in descending order irrespective of cultured and wild ones. The richest mineral contained in the roots was noticed to be K and followed by Mg and Ca. Generally increased tendency of crude protein, fat, ash, K, Mg, Ca, Mn, Zn, Cu and P contents were observed with older roots, however, decreased total sugars and Fe content. Lead and cadmium content was far bellow the authorized tolerance limits. The quantitative fractionation of the protein of the roots ranked albumin the highest content, followed by globuin, prolamin and glutelin. Decreased albumin content was observed with the older age roots, while increased globulin, prolamin and glutelin content. The minimum solubility of the soluble protein of the roots was found to be at pH 4.0 and maximum, at pH 10.0. Disc gel electrophoresis of the soluble protein of C. lanceolata roots showed almost similar patterns and numbers of bands. The molecular weight for main band protein was estimated to be about 90,000.
년근별(年根別)에 따른 더덕의 일반성분(一般成分), 무기질(無機質) 및 단백질(蛋白質) 성분(成分)을 atomic absorption spectro-photometer, spectrophotometer 및 disc gel electrophoresis에 의한 분석(分析) 결과(結果)는 다음과 같았다. 일반성분(一般成分)은 재배더덕이나 야생더덕에 관계없이 총당(건물중)이 가장 많이 함유된 성분이고 1년근이 68.76%, 5년근이 66.54%로써 재배 년령이 높아짐에 따라 다소 함량이 감소되는 경향이었다. 그 다음 조단백질, 조섬유, 조지방, 회분의 순으로 함유되었고 조섬유를 재외하고는 재배더덕이 야생더덕 보다 그 성분함량이 다소 높았고 재배 년령이 높아짐에 따라 함량이 높아졌으나 조섬유는 별로 증가가 없었다. 무기성분은 K의 함량이
