| ABSTRACT: The plant, Amburana cearensis A. C. Smith (Fabaceae), commonly called cumaru, is widespread in the Caatinga cearense, a less known ecosystem in Brazil. A. cearensis is rich in several compounds like protocatechuic acid, tannins, coumarin, flavonoids and phenolic heterosides, such as amburosides A and B, that have been isolated. The aim of this study was to determine the antimicrobial potential and draw the chemical profile of the distinct characteristics of A. cearensis stem bark decoction, for its possible potential as a food conservation agent. The chemical compounds were characterized by one- and two-dimensional 1H and 13C NMR analyses and Liquid Chromatography-Mass Spectrometry (LCMS). The compounds of coumarin, amburosides A and B, and... |

| ABSTRACT Plant diversity around the world, as well as the chemical variation, involves a large amount of bioactive substances. The use of plant extracts with biological properties appears as a viable and healthy alternative when compared to synthetic substances. In this context, the objective of this study was to evaluate the aqueous extracts of native and cultivated leaves of Physalis angulata L., as well as the influence of the extraction method on the bioaccessibility of bioactive compounds, antioxidant activity and antimicrobial activity. The extracts were obtained from the native and cultivated leaves of P. angulata using three different extraction methods: decoction, maceration and an ultrasound-assisted method. The analysis of variance showed... |
