The antioxidant and anticancer activities of Phellinus linteus, Inonotus obliquus, and Pleurotus ostreatus according to extraction methods were measured. The contents of polyphenolic compounds were higher in fermented extracts than those in water extracts. The contents were 192.4mg/100 ml for Inonotus obliquus vinegar, 186.9 mg/100 ml for Phellinus linteus vinegar, and 156.5 mg/100 ml for Pleurotus ostreatus vinegar, respectively. EDA(electron donating ability) in Phellinus linteus that was highest among mushrooms was 83.9% in the water extract and 96.8% in the fermented extract. The growth of stomach cancer cells, SNU-719 was inhibited 62.4%, 65.5%, and 53.0% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, respectively and also the growth of liver cancer cells, Hep3B was inhibited 67.1%, 68.3%, and 57.6% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, while the growth of normal cell, DC2.4 was not affected. Even though Phellinus linteus and Inonotus obliquus showed higher inhibition in cancer cell growth, Pleurotus ostreatus can be efficiently used for antioxidant and anticancer activities due to their cheap price in the market.

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 Agrimony (Agrimonia pilosa L.) and Chinese lizardtail (Saururus chinensis Baill) according to extraction methods were measured. SOD-like activity showed greater antioxidant effects with ethanol solvent than those with water. Ethanol extracts of Agrimony leaves showed the highest SOD-like activity of 94.4%. SOD-like activity differed according to the extraction solvents. The contents of polyphenolic compounds were higher in water extracts than those in ethanol extracts. The contents were 161.4 mg for Agrimony roots, 100.2 mg for Agrimony leaves, and 79.1 mg for Agrimony stalks in order. EDA in Agrimony leaves that were highest among medicinal plants were 83.4% in the water extract and 81.7% in the ethanol extract. The anticancer effects of the extracts by water and ethanol from Agrimony and Chinese lizardtail were experimented. The growth of stomach cancer cells, SNU-719 was inhibited 94.5% by the hexane fractions of Agrimony and also the growth of liver cancer cells, Hep3B was inhibited 83.2% by the hexane fractions of Agrimony, while the growth of normal cell, DC2.4 was not affected.
