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... |

Abstract The main objective of this study was to demonstrate the antimicrobial potential of the crude extract and fractions of Chenopodium ambrosioides L., popularly known as Santa-Maria herb, against microorganisms of clinical interest by the microdilution technique, and also to show the chromatographic profile of the phenolic compounds in the species. The Phytochemical screening revealed the presence of cardiotonic, anthraquinone, alkaloids, tannins and flavonoids. The analysis by HPLC-DAD revealed the presence of rutin in the crude extract (12.5 ± 0.20 mg/g), ethyl acetate (16.5 ± 0.37 mg/g) and n-butanol (8.85 ± 0.11 mg/g), whereas quercetin and chrysin were quantified in chloroform fraction (1.95 ± 0.04 and 1.04 ± 0.01 mg/g), respectively. The most... |
