dc.description.abstractPyrostegia venusta (Ker-Gawl.) Miers (Bignoniaceae) is a species with a wide distribution in nearly all of Southern and Southeastern Brazil, has long been used in folk medicine and is considered an invasive plant. The phytotoxic potential of a hydroalcoholic extract of the flowers of P. venusta was evaluated by the germination (pre and post-emergence) and the phytotoxicity bioassays (mitotic index) on the test plant Lactuca sativa (Asteraceae) (lettuce). A phytochemical screening was performed to identify the components of the floral extract. Different concentrations of the extract caused changes in the germination parameters, the root length and the mitotic index. The phytochemical screening indicated the presence of substances such as terpenes, sterols, flavonoids, tannins and saponins, which are compounds that may be associated directly with the results of cytotoxicity and phytotoxicity observed. P. venusta has allelochemical components capable of impairing the germination and root growth of lettuce.
