The Chemical Composition of Taraxacum officinale Consumed in Korea
한국산 서양민들레(Taraxacum officinale)의 화학적 조성
Abstract
For centuries, dandelion(Taraxacum officinale) is widely used as a food and a medicinal herb. However, there is inadequate documented information on the chemical composition of T. officinale consumed in korea. This study was attempted to analyze proximate component, amino acid, free sugar, mineral and fatty acid composition in T. officinale to establish the value as an useful food material. Moisture, ash, crude protein and fat contents in leaf are 7.85, 11.35 21.6 and 5.12%, respectively. Moisture and ash contents of root were 7.73 and 4.82%. Crude protein and fat contents of root were 11.8 and 1.73%, respectively. The major free amino acid was asparagine, arginine, serine and proline etc. The total contents of free amino acid in leaf and root were 1476.98 and 2710.06 mg%, respectively. The major free sugar in T. officinale was glucose, fructose, sucrose and maltose. Sucrose was also detected in a large amount. The major fatty acid of T. officinale are palmitic acid, stearic acid, oleic acid, linoeic acid and linolenic acid. The fatty acid compositions of leaf and root were different each other. Linolenic acid(63.6%) was the major fatty acid of the leaf and linoleic acid(56.4%) was the major fatty acid of the root. Most of mineral contents were high in leaf and root. Especially K content was higher in leaf than root.
천연에 널리 존재하지만 미개발 자원인 서양민들레의 식품학적 가치와 식품소재로의 개발가능성을 검토하기 위하여 민들레의 성분을 분석하였다. 그 결과, 민들레의 일반성분은 잎과 뿌리에서 각각 수분 7.85와 7.73%, 회분 11.35와 4.82%, 조단백 21.6과 11.8%, 조지방 5.12와1.73%로 뿌리보다는 잎에서 높은 함량을 나타내었다. 민들레 잎과 뿌리의 유리아미노산 함량은 뿌리가 2710.66mg%로 잎의 1476.98mg% 보다 높았고, asparagine, arginine, serine, proline등이 많이 함유되어 있었다. 필수아미노산 함량은 잎에서 233.83mg%, 뿌리에서 209.76mg%로 잎에서 그 함량이 많았으며, 잎과 뿌리 모두 valine과 threonine의 함량이 많았다. 유리아미노산 유도체로는
