Optimization of ultrasonic-assisted extraction of phenolic compounds from Justicia spicigera leaves
(Springer Singapore, 2023)
Optimal operational variables of phenolic compound extractions from pistachio industry waste (Pistacia vera var. Kerman) using the response surface method
(Springer, 2020-07)
San Juan is a leading pistachio producer in Argentina. Pistachio industrial processing generates biowastes that can be reused. These biowastes can be used as a precursor of bioactive components of interest as the phenolic ...
Ultrasonic-assisted extraction of anthraquinones from Heterophyllaea pustulata Hook f. (Rubiaceae) using ethanol-water mixtures
(Elsevier Science, 2015-02)
In this study, ultrasound-assisted extraction (UAE) was evaluated as an easier and more efficient alternative method for the isolation of anthraquinones (AQs) from Heterophyllaea pustulata Hook f. (Rubiaceae), compared ...
Extraction of recombinant proteins from Escherichia coli by cell disruption with aqueous solutions of surface-active compounds
(2018-07-01)
BACKGROUND: Green fluorescent protein (GFP) is used extensively as a biomarker due to its unique spectral and fluorescence characteristics. GFP is usually obtained from recombinant strains of Escherichia coli (E. coli) ...
Avaliação das condições de extração para posterior especiação de arsênio em alimentos por LC-ICP-MS
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2019-07-29)
Arsenic is a toxic element with carcinogenic and mutagenic characteristics. However,
its toxicity is associated with their species, because some present different toxicities.
In this sense, speciation analysis is mandatory ...
