dc.description.abstractToday, a great interest in Jatropha-based products exists worldwide, mainly for the production of biofuel. However, the oil obtained from this plant is known to be toxic due to contained curcins and phorbol esters. Bioassays, including plant cytogenetic assays based on cell cycle observation, are useful for determining the toxicity of J. curcas oil. Hence, the aim of this study was to describe the mechanism of action of J. curcas oil by cell cycle analysis using Lactuca sativa as plant testing model. A decrease in root growth was observed, closely related to the reduction in mitotic index, along with an increase in condensed nuclei. J. curcas chemicals act both as aneugenic agents, leading to the formation of lagged, sticky chromosomes and c-metaphase cells, as well as clastogenic agents, inducing the formation of chromosome bridges and fragments. The cytotoxicity and genotoxicity of phorbol esters and other chemical components of J. curcas oil was determined and discussed.pt_BR
