Arrabidaea Chica

The species Arrabidaea chica (Humb. & Bonpl.) B. Verl. (Bignoniaceae) is a plant native to tropical forests, popularly known as pariri or crajiru, and it is widely used in folk medicine to treat inflammatory diseases, anemias, skin diseases and to assist in the treatment of leukemia. Because of the widespread use of the plant, concern with its quality and effectiveness is fundamental. This study demonstrates the application of mass spectrometry with ionization by paper spray (PS-MS) as a chemical characterization method to evaluate the presence of the active principles in teas prepared by infusion from commercial samples of the medicinal plant Arrabidaea chica by infusion. The analyses of the samples were performed in two periods: 24 hours and 15 days after the preparation of the teas. Compounds referring to the class of substances 3-deoxythocyanidins were detected without any pre-treatment of the sample or chromatographic separation to provide valuable information for the evaluation and quality control of this product. Significant changes in the m/z signals of greater intensity, referring to the class of 3-deoxythocyanidins, were observed in the mass spectra, and multivariate analysis corroborated the degradation of this class of substances with time, resulting in a probable loss of the quality and effectiveness of the tea.
