초록
예로구터 그 수액이 건강보조식품으로 사용되어온 고로쇠나무의 줄기를 대상으로 항산화 활성을 가지는 성분을 찾기위하여 실험에 착수하였으며, 그 MeOH추출물의 ETOAc분획을 대상으로 Column chromatography를 실시하여 scopoletin, isoscopoletin, (-) -epicatechin등 3종의 화합물을 분리하고 항산화 활성을 측정하였다. 이중 scopoletin과 isoscopoletin은 BHA나
One flavan 3-ol derivative was isolated from the stem of Acer mono Max, along with two known coumarins. On the basis of spectroscopic evidence, the structures of these compounds were established as (-) - epicatechin, scopoletin and isoscopoletin. Antioxidative activity of (-) - epicatechin was examined by the DPPH free radical scavenging method. Antioxidative activity of (-) - epicatechin
