초록

머위의 뿌리, 줄기, 잎을 사용하여 추출물에 따른 항산화 활성을 분석하였고, 추출물을 분획 정제하여 암세포 생장 억제성을 실험하였다. SOD 유사활성은 머위 잎의 에탄올 추출물이 96.7%의 가장 높은 활성을 보였으며, 추출 용매에 따른 머위의 SOD 유사활성은 물 추출보다는 에탄올 추출물이 더욱 높은 항산화 활성을 나타냈다. 총폴리페놀 함량은 물 추출물에서 전체적으로 높은 함량을 나타내었으며, 머위 잎이 223mg/g dry weight으로 가장 높았다. 시료별로 전자공여능 효과를 살펴보면 머위 뿌리의 물 추출물에서 61.5%, 머위 잎의 에탄올 추출물에서 34.9%로 가장 높은 전자공여능을 나타냈다. 암세포 생존 억제성의 실험에서 머위 추출물의 분획물들은 정상세포 DC2.4의 생육에는 크게 영향을 미치지 않으면서도 위암세포주 SNU-719의 생육은 41.9%로 크게 억제시켰고, 간암세포주 Hep3B의 생육은 72.7% 억제시켰다. 본 연구 결과들을 종합해 볼 때 머위를 이용한 새로운 기능성 식품 소재 및 약용자원식물로 개발이 가능하다.

The antioxidant activities of the extracts of butterbur (Petasites japonicus) derived from different extraction methods were investigated. SOD (superoxide dismutase)-like activity differed according to the extraction solvents, showing a greater antioxidant effect with ethanol solvent than that of water. Ethanol extracts of butterbur leaves showed higher SOD-like activity of 96.7% than those of water extracts. The contents of polyphenolic compounds were higher in water extracts than those in ethanol extracts. The highest content of polyphenolic compounds was 223mg/g dry weight for butterbur leaves. EDA of butterbur roots was 61.5% in the water extract and EDA in butterbur leaves was 34.9% in the ethanol extract. The anticancer effects with the extracts of butterbur were experimented by fractionations with different solvents. 41.9% of the growth of stomach cancer cells, SNU-719, were inhibited and also 72.7% of the growth of liver cancer cells, Hep3B, were inhibited by the butanol fractions of butterbur, while not affecting the growth of normal cell, DC 2.4.
