Plants are potential sources of bioactive molecules. According to the Dictionary of Natural Products, around 84% of the bioactive compounds contain at least a hydroxyl group or an amine group in their structure. Previously, we had investigated the antioxidant properties of Zinnia peruviana (L.) L. (Asteraceae), and promising results were obtained. It is well-accepted that the antioxidant activity is markedly influenced by the presence of hydroxyl groups in a chemical structure. In this sense, in the present work we investigate the antioxidant properties and the cytotoxic activity of Z. peruviana extracts.Z. peruviana ?chinita del campo? is a traditional argentinean herb and antimalaric properties have been reported.
