Avaliação do potencial antioxidante dos extratos aquoso e etanólico de Mentha pulegium, Uncaria tomentosa e Phyllanthus niruri frente às alterações induzidas por T-butil hidroperóxido em eritrócitos humanos in vitro
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2016-07-27)
The stone cruscher (Phyllanthus niruri), cat'sclaw (Uncaria tomentosa) and pennyroyal (Mentha pulegium)have been used by people to treat a variety of diseases associated with oxidative stress. In this study, we aimed to ...
A new and efficient methodology for olefin epoxidation catalyzed by supported cobalt nanoparticles
(Beilstein-Institut, 2021-02-22)
A new heterogeneous catalytic system consisting of cobalt nanoparticles (CoNPs) supported on MgO and tert-butylhydroperoxide (TBHP) as oxidant is presented. This CoNPs@MgO/tBuOOH catalytic combination allowed the epoxidation ...
Limonene oxyfunctionalization over Cu-modified silicates employing hydrogen peroxide and t-Butyl hydroperoxide: Reaction pathway analysis
(Elsevier B.V., 2018-11-14)
Limonene oxidation over Cu-nanostructured mesoporous materials was studied. Three solids with different copper content were synthesized employing the template-ion exchange method, and physically-chemically analyzed by a ...
Estudos sobre a aplicação de óxido de nióbio em reações de oxidação de compostos orgânicos
(Universidade Estadual Paulista (Unesp), 2018-02-26)
Os hidrocarbonetos se constituem na função mais simples da química orgânica. Mesmo sendo formados apenas por carbono e hidrogênio, esta classe é uma das mais diversas, onde se destacam os hidrocarbonetos alquil aromáticos ...
Amorphous Cr/SiO2 Materials Hydrothermally Treated: Liquid Phase Cyclohexanol Oxidation
(Springer, 2018-07)
Amorphous Cr–SiO2 materials were synthesized by the sol–gel method and hydrothermally treated at temperatures between 150 and 220 °C. These materials were used as catalysts for cyclohexanol oxidation with H2O2 as oxidant ...
