1. Fast and Ecological Liquid-Liquid Separation Method for Preparing Quinones Enriched Extract from Nigella sativa Oil
A fast, inexpensive, and ecological method based on liquid-liquid extraction principle has been developed for preparation of extract with high content of Nigella sativa (N. sativa) quinones. The gas chromatography-mass spectrometry (GC-MS) analysis showed that oil extraction using 70% ethanol for 6 h yielded extract containing 50% of thymoquinone (TQ) and 13

2. DETERMINAÇÃO DE DISRUPTORES ENDÓCRINOS EM FILÉ DE PEIXE UTILIZANDO QuEChERS MODIFICADO E GC-(TQ)MS/MS / DETERMINATION OF ENDOCRINE DISRUPTERS IN FISH FILLET BY MODIFIED QuEChERS AND GC-(TQ)MS/MS
Compostos conhecidos como disruptores endócrinos (DEs), tais como agrotóxicos, alquilfenóis, hormônios, dentre outras classes de substâncias são responsáveis pela alteração de funções do sistema endócrino. Esse efeito ocorre quando os DEs interagem com os receptores hormonais, alterando os padrões de resposta natural do sistema endócrimo. Os or

3. SIMULTANEOUS DETERMINATION OF ORGANIC COMPOUND RESIDUES IN WATER SAMPLES BY DISPERSIVE LIQUIDLIQUID MICROEXTRACTION (DLLME) AND GC-(TQ)MS/MS / DETERMINAÇÃO DE RESÍDUOS DE COMPOSTOS ORGÂNICOS EM ÁGUA POR MICROEXTRAÇÃO LÍQUIDO-LÍQUIDO DISPERSIVA (DLLME) E GC-(TQ)MS/MS
The use of chemicals, which generates a lot off benefits, is responsible for the contamination of soil, water and foods. The concern about contamination of surface and ground water systems by pesticides has grown in scientific circles, especially by the presence of pesticides and other compounds in water sources. Thus, rapid analytical methods, sensitive and
