Abstract

The purpose of this study is to determine the possibility of using Codonopsis lanceolata leaves as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Codonopsis lanceolata leaves were measured. The contents of carbohydrate, crude protein, crude lipid and ash were 65.09%, 18.02%, 1.34% and 9.72%. And the calories of Codonopsis lanceolata leaves were 288.36 Kcal. The protein contained total 16 different kinds of amino acids. The contents of essential and non-essential amino acids were 5,906.41 mg and 7,551.56 mg, respectively. K was the most mineral followed by Ca, P, and Mg, which means Codonopsis lanceolata leaves are alkali material. Total phenolic contents of Codonopsis lanceolata leaves were 1.87 mg/g, and total flavonoids contents were estimated as 1.87 mg/g. Based on the above results, we deemed that the Codonopsis lanceolata leaves might have potential antioxdant activities. The general nutrients and other antioxidatant bioactive materials in Codonopsis lanceolata leaves were also potential materials for good health food. It is expected that a follow up study of Codonopsis lanceolata leavesthrough developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.

본 연구는 더덕 잎의 기능성식품 및 화장품 소재로서의 이용가능성을 조사하기 따라서 더덕 잎의 영양성분 분석을 통한 식품영양학적 접근, 생리활성 기능을 기대할 수 있는 관련 물질 함량의 분석하였다. 식품영양학적 접근에서의 더덕 잎의 일반성분은 건량기준으로 탄수화물 69.12%, 조단백질 19.14%, 조지방 1.42% 및 조회분 10.32%이었고 더덕 잎 100 g의 함유 열량은 288.36 kcal로 분석되었다. 또한, 필수아미노산과 비필수아미노산 함량은 각각 5,906.41 mg, 7,551.56 mg이었고, 무기질 중 칼륨의 함유량이 가장 높았고 그 다음이 칼슘, 인, 마그네슘 순으로 나타나 알칼리성 재료임을 알 수 있었다. 유리당의 경우 sucrose의 함량이 전체 유리당의 약 42%를 차지하고 있는 것으로 나타났으며, 더덕 잎의 조사포닌 함량은 97.51 mg/g을 함유하고 있는 것으로 나타났다. 더덕 잎의 총 페놀 함량은 1.87 mg/g, 플라보노이드 함량은 0.61 mg/g으로 분석되었으며, DPPH 소거 활성을 농도별로 측정하여 비교한 결과 $1,000{\mu}g/mL$ 농도에서 64.32%의 활성을 보였다. 이상의 결과로부터 더덕 잎 추출물은 항산화능이 있음을 확인할 수 있었다. 따라서 더덕 잎을 식품 첨가물로서, 혹은 다른 약용으로의 조리 된 식품으로써의 활용가능성이 있을 것으로 판단된다.
