| Potent Free Radical Scavenging Activity of Propol Isolated from Brazilian Propolis  | | | | Abstract
| We evaluated free radical scavenging activity of the water, methanol and chloroform ex tracts of propolis in l,l-diphenyl-2-picrylhydrazyl (DPPH) free radical and xanthine-xanthine oxidase (XO D) generated superoxide anion assay systems. The free radical scavenging activ ity guided fractionation and chemical analysis led to the isolation of a new compound, propol {3-[4-hydroxy-3-(3-oxo-but-l-enyl)-phenyl]-acrylic acid) from the water extract, which was more potent than most common antioxidants such as vitamin C and vitamin E (a-tocopherol) in these assay systems. | | | |
