    Mutagenicity of plant flavonoids: structural requirements for mutagenic activity in Salmonella typhimurium.[Pubmed: 368618]

    METHODS AND RESULTS:
    40 compounds structurally related to the plant flavonol quercetin were tested for mutagenic activity in Salmonella typhimurium strain TA98. 10 flavonols, quercetin, myricetin, rhamnetin, galangin, kaempferol, tamarixetin, morin, 3'-O-methylquercetin, 7,4'-di-O-methylquercetin and 5,7-di-O-methyl-quercetin, exhibited unequivocal mutagenic activity.
    CONCLUSIONS:
    4 compounds, quercetin, myricetin, rhamnetin and 5,7-Di-O-methylquercetin, were active without metabolic activation, although metabolic activation markedly enhanced their activity.

    Use of the SOS-chromotest spot assay as a screening system for detecting genotoxic compounds in crude plant extracts.[Pubmed: 11827573]

    METHODS AND RESULTS:
    An SOS-chromotest spot assay was used to detect genotoxic compounds in crude plant extracts. The method allows simultaneous testing of extracts from different species in either a liquid or a solid crystalline form. Extracts from two species of the genus Senna, native to the state of Morelos, Mexico, were assayed. Four genotoxic compounds were isolated, and were identified as quercetin and rutin from S. wislizeni, and 5,7-di- O-methylrutin and 5,7-Di-O-methylquercetin from S. skinneri.
    CONCLUSIONS:
    The SOS-chromotest spot assay proved to be useful for activity- guided fractionation at the beginning of screening for genotoxic compounds in crude plant extracts.
