칡(kudge)은 무엇인가? | 칡(kudge)은 다년생 식물로서 굵은 줄기로 이루어져 나무로 분류된다. 이는 오래전부터 자양강장제 등 건강식품으로 이용되었으며 특히 뿌리부분은 항산화 물질이 다량 함유되어있어 최근 많은 연구가 이뤄지고 있다[1-2]. | |
칡에는 어떤 성분이 함유되어 있는가? | Iso-flavone은 일반 세포 내에서 estrogen receptor와 결합할 수 있는 능력이 있으며 체내에서 심장병, 골다공증의 발생 빈도를 낮춰주며 여러 갱년기 증상을 완화시켜 주는 것으로 알려졌다[3-4]. 칡에는 다량의 전분 외에 iso-flavone계 성분인 puerarin, daidzein, daidzin, genistein, genistin, formonetin, coumesterol, 4’-7-dihydroxyisoflavone, 7-xyloside puerain, 3’-hydroxypuerain, 3’-methoxypuerin, β-sitostrol, lupeol, lupenone, allantoin 등이 함유되어 있다[5-6]. | |
반응표면분석법의 장점은 무엇인가? | 반응표면분석법은 통계학적 분석방법으로 기초실험을 통해 변수에 따른 반응결과 값을 예측하여 원하는 반응치에 따른 최적조건을 도출해주는 방법이다. 따라서 이는 복잡한 process들을 최적화하는데 매우 효과적이고 체계적인 기술이며 실험에서의 각 independent variables에 따른 효과와 최적조건들을 빠른 시간에 효율적으로 찾는데 많이 활용된다[18-19]. 본 연구에서는 기초실 험을 바탕으로 반응표면분석법을 활용하여 실험횟수를 줄이고 원하는 결과값을 도출하는 최적공정조건을 분석했다. |
