西班牙语; 卡斯蒂利亚语. The aqueous extract of Phyllanthus orbicularis contains bioproducts able tosignificantly reduce the mutagenesis mediated by oxidative compounds. Abioactive-directed fractionation of the aqueous extract of P. orbicularis hasbeen applied with the aim of identifying antimutagenic fractions, which al-lowed isolating and identifying some biocompound responsible for this activ-ity. Antimutagenesis of all fractions was determined by the Salmonellaretromutation assay, using hydrogen peroxide as model mutagen. Applyingthis methodology, two potent antimutagenic fractions have been obtainedable to totally abolish the mutagenicity produced by hydrogen peroxide. Inthese fractions 2,4-di-tertbutylphenol, OO’-diphenol-4,4’,6,6’-tetra-tert-butyland 2,6-di-sec-butylphenol were identified by Gas Chromatography/MassSpectrometry
