| Abstract: | In this paper,the crude rasveratrol from wine grape pomace using methanol extraction was purified by silica gel column chromatography. Then, the antioxidant activity of resveratrol was investigated, including oxygen radical capacity and 2,2-diphenyl-l-picrylhydrazyl(DPPH) radical scavenging capacity. The results indicated that resveratrol had significant scavenging and antioxidant activity and those antioxidant properties of resveratrol depended on concentra-tion and increased with the increasing concentration of sample. |
| Keywords: | wine grape pomace resveratrel antioxidant activity free radical scavenging capacity |
