초록
본 연구에서는 항산화성분 함량이 높다고 알려진 천연물인 감잎, 엉겅퀴, 뉴그린을 이용하여 유효성분을 추출하고 DPPH radical scavening activity와 플라보노이드성분 함량분석을 수행하였다. 추출에 사용된 추출용매로는 초순수와 주정을 이용하였고, 초순수-주정의 비율, 시료의 양, 추출시간, 추출온도 등을 변수로 설정하였다. 각 천연물의 최적추출조건은 추출시간(2.5~3.5 h), 시료의 양은 50 g/L이었고, 주정/초순수의 부피비와 추출온도의 경우 각각 감잎(55~65 vol%, 50~60 ℃), 엉겅퀴(40~50 vol%, 55~65 ℃), 뉴그린(55~65 vol%, 50~60 ℃)으로 나타났다. 또한 추출된 유효성분의 항산화능과 플라보노이드성분 함량분석 결과 감잎 > 엉겅퀴 > 뉴그린 순으로 크게 나타났다.
In this study, we extracted active components from thistle, persimmon leaf, and new green which are known to have a high content of antioxidants and also analyzed the 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavening activity and flavonoid content. Both ultrapure water and alcohol were used as extraction solvents and the ratio of both solvents, sample, amunts extraction time, and extraction temperature were varied. The optimal extraction condition of each natural compounds were 2.5~3.5 h of the extraction time and 50 g/L of the sample amount. The optimal ratio of ultrapure water and alcohol and extraction temperature were as follows; persimmon leaf (55~65 vol%, 50~60 ℃), thistle (40~50 vol%, 55~65 ℃) and new green (55~65 vol%, 50~60 ℃). In addition, the antioxidant capacity and flavonoid content of the extract increased in the order of persimmon leaf, thistle, and new green.
