Abstract
Natural matrices represent a rich source of biologically active compounds and are an example of molecular diversity, with recognized potential in drug discovery. In the present work, the infusions of Matricaria recutita L. (German chamomile) and Chamaemelum nobile L. (Roman chamomile) were submitted to an analysis of phenolic compounds and evaluation of bioactivity. Phenolic compounds were characterized by reversed-phase high performance liquid chromatography coupled to diode array detection and mass spectrometry with electron spray ionization (HPLCDAD/ ESI-MS). The bioactivity of the samples was tested in different human tumour cell lines (breast- MCF-7, lung- ...
