Abstract

Folk medicinal plants have been analyzed and assayed to confirm their possible antitumoral and anticarcinogenic properties. Aveloz is a plant of the genus Euphorbia (Euphorbiaceae) and it has been popularly used in South America for treating ulcer, cancer, tumor, wart and other diseases. However, some researches have shown opposite effects. Due to these contradictory results, the aim of this work was to test the antimutagenic potential of Euphorbia tirucalli latex in Aspergillus nidulans methionine system. Two concentrations of the latex were used in conidia treatment: 0.1% and 0.2% (v/v). The treatment was developed by collecting quiescent conida from five days old colonies in latex solution, during 24 hours. The results have indicated that both concentrations show antimutagenic effect because the mutation frequency of the treated conidia was smaller than mutation frequency of the control
