Characterization of proanthocyanidins from Parkia biglobosa (Jacq.) G. Don. (Fabaceae) by flow injection analysis - Electrospray ionization ion trap tandem mass spectrometry and liquid chromatography/electrospray ionization mass spectrometry

The present study investigates the chemical composition of the African plant Parkia biglobosa (Fabaceae) roots and barks by Liquid Chromatography - Electrospray Ionization and Direct Injection Tandem Mass Spectrometry analysis. Mass spectral data indicated that B-type oligomers are present, namely procyanidins and prodelphinidins, with their gallate and glucuronide derivatives, some of them in different isomeric forms. The analysis evidenced the presence of up to 40 proanthocyanidins, some of which are reported for the first time. In this study, the antiradical activity of extracts of roots and barks from Parkia biglobosa was evaluated using DPPH method and they showed satisfactory activities.

O mito de don juan e a subjetividade moderna

The legendary Don Juan character inhabits the popular imaginary with such a vibrancy of a myth, despite its slight recognition as such by the scientific literature. The purpose of this article is to verify if Don Juan’s play can be understood, scientifically, as a modern myth, as well as understand its mythical nature and its relation to the modern man. A structural and historical analysis of the two first plays on Don Juan has guided us: the one written by Tirso de Molina in 1630, and the one by Molière, written in 1665. The studies allow us to say that Don Juan is a typical modern myth, once it is constituted by narratives that expose a world looming under the signs of individualism, hedonism, arrogance and audacity forged under the appeals of sexual desire.
