Abstract
|
|
|
|
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 (RC_{50};:;7.5;{mu}g) was more greater than those of {alpha}-tocopherol;(RC_{50};:;12;{mu}g) and BHA;(RC_{50};:;14;{mu}g).
