title: In vitro breast cancer cell lethality of Brazilian plant extracts.
abstract: In this study we screened the cytotoxicity of 1220 plant extracts obtained from 351 plants belonging to 74 families occurring in the Amazon and Atlantic rain forests against MCF-7 human breast adenocarcinoma cell lines. All extracts were tested at a dose of 100 microg/mL. Only 11 aqueous or organic extracts belonging to the Annonaceae, Apocynaceae, Araceae, Clusiaceae, Flacourtiaceae, Leguminosae, Olacaceae and Violaceae showed marked lethal activity. Vismia guianensis and Annona hypoglauca extracts showed the greatest lethal activity.
