Extracts from leaves, stems, and roots of twelve plants used commonly in Yucatecan traditional medicine were evaluated in the DNA-methyl green assay. Twenty one extracts showed DNA-interacting activity, and nine of them, belonging to five plant species, presented a displacement activity of 5% or higher. The highest activity (17.6%) was detected in the leaf extract of Heliotropium angiospermum.
