Phoradendron latifolium (SW) Griseb. is one of many species of mistletoe growing wild in Brazil. The plant used in our experiments was gathered in Maringá-Paraná where it is found growing on the stacks and branches of different hosts.
Two ethanolic extracts were prepared using dried and milled leaves. The solvent was evaporated in vacuum. The residue of the first extract was dissolved with propylene glicol, the other residue, after washed with chloroform was dissolved in the same vehicle. Both extracts showed hipotensive response when tested on nembutal anaesthetized rats. The phytochemical screening revealed the presence of volatile and non volatile acids, amino groups, steroids, phenols, gums, mucilage, condensed tannins and heterosidic anthraquinones, flavones and non-haemolytic saponines.
