한국산 갓(Brassica juncea Cosson)의 화학성분에 관한 연구 = Studies on the Chemical Components of Korean Brassica juncea Cosson

국문 초록 (Abstract)

한국산 갓(Brassica juncea Cosson)의 주요 화학적 성분들을 조사하기 위하여, 일반성분, 무기질, 유리당, 유기산 및 유리아미노산을 분석하였다.
9가지 갓품종의 일반성분 함량은 수분 87.5%, 조단백 2.9%, 조지방 0.5%, 탄수화물(당질) 5.6%,조섬유 2.1%, 조회분 1.4%였다. 돌산 갓의 잎줄기의 무기질함량은 Ca137.6mg%, Mg 17.2mg%, Na 14.4mg%, Fe7.0mg%였으며 pH,적정산도, 알카리도는 각각 5.8, 7.2, 8.4였다. 유리당은 주로 glucose 로서 잎줄기의 함량은 29.3mg%였으며, 유기산은 malic acid, citric acid, oxalic acid, ascorbic acid 등이 확인되었으며, 각각의 함량은 49.1mg%, 12.4mg%, 23.8mg%, 19.3mg%였다. 유리 아미노산은 15가지가 확인되었으며, 잎이 줄기보다 훨씬 함량이 많았고 aspartic acid, glutamic acid,serine, proline,arginine 등이 주요 아미노산으로 100∼600mg%의 함량을 나타내었다.

For the investigation of major chemical components in korean mustard leaf(Brassica juncea Cosson ), its proximate composition and contents of minerals, free sugars, organic acids and free amino acids were analyzed.
The proximate compotion of leaves in 9 varieties of B. juncea Cosson were moisture-87.5 %, crude protein-2.9 %, crude lipid-0.5 %,carbohydrate(sugars)-5.6%, crude fiber-2.1 %, and crude ash-1.4%.Several components of mustard leaf Dolsan were as follows:
The mineral contents of blade -leaf stalk in mustard leaf Dolsan were Ca-137.6mg %,Mg-7.2mg%,Na-14.4mg% and Fe-7.0mg%. pH,titrable acidity and alkalinity were 5.8,7.2 and 8.4,respectively.
The content of major free sugar was only glucose-29.3mg%.
The contents of major organic acids were confirmed to be malic acid-49.1mg%,citric acid-12.4mg%,oxalic acid-23.8mg%,and ascorbic acid-19.3mg%.
Fifteen kinds of free amino acids were identified, and their contents in blade were higher than those in leaf stalk.
Major free amino acids were aspartic acids, glutamic acid, serine,proline and arginine, andtheir condents were in the range of 250 -600mg%.
