| Antioxidative Activity of Leguminous Seed Extracts Evaluated by Chemiluminescence Methods  | | | | Abstract
| The antioxidant properties of extracts from seeds of white bean, pea, lentil, everlasting pea, faba bean, and broad bean were investigated by enhanced chemilumi nescence (ECL) and photochemiluminescence (PCL) methods. All extracts exhibited antioxidative activity. The antioxidative efficacy of the extracts investigated varied markedly and did not dependent upon their content of phenolic compounds. Results of TLC analysis of the extracts indicated that the antioxidant activity originated from several phenolic compounds, partly sim ilar in their polarity. | | | |

| 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. | | | |
