Evolution of anthocyanin content during grape ripening and characterization of the phenolic profile of the resulting wine by comprehensive two-dimensional liquid chromatography. Author(s): LAGO, L. O.; SWIT, P.; SILVA, M. M. da; BIASOTO, A. C. T.; WELKE, J.; MONTERO, L.; HERRERO, M. Abstract: The typical phenolic profile in grapes is characterized by its complexity both in terms of number of diverse chemical structures and their variation during ripening. Besides, the specific ph... ... Repository: BDPA Publication year: 2023
Determination of herbicides in human urine by liquid chromatography-mass spectrometry with electrospray ionization. Author(s): JARDIM, I. C. S. F.; POZZEBON, J. M.; QUEIROZ, S. C. do N. de Repository: BDPA Publication year: 2006
A rapid ultrasound-assisted dispersive liquid-liquid microextraction followed by liquid chromatography coupled to a mass spectrometry for determination of artemisinin in tilapia muscle. Author(s): SOARES, M. P.; SHIROMA, L. S.; CARDOSO, I. L.; SAMPAIO, F. G.; JONSSON, C. M.; RANTIN, F. T.; QUEIROZ, S. C. do N. de Intensive aquaculture represents stressful conditions for fish and can trigger diseases that negatively affect their performance and survival. Fish production requires greater control, with improved h... ... Repository: BDPA Publication year: 2019
Verification of the selectivity of a liquid chromatography method for determination of stilbenes and flavonols in red wines by mass spectrometry. Author(s): SILVA, L. F. da; GUERRA, C. C.; FORESTI, A.; BERGOLD, A. M. Quantification of bioactive phenols, like stilbenes and flavonols (SaF), has been conducted to evaluate the nutraceutical potential of red wines. However, there is still a lack of full validated, fast... ... Repository: BDPA Publication year: 2016
Determination of pesticides in water by liquid chromatography-(Electrospray Ionization)-mass spectrometry (LC-ESI-MS). Author(s): QUEIROZ, S. C. do N. de; LAZOU, K.; SANDRA, P; JARDIM, I. C. S. F. A method for determination of a selected group of pesticides in water (tap and ground water) was developed using liquid chromatography-(electrospray ionization)-mass spectrometry (LC-ESI-MS). The pest... ... Repository: BDPA Publication year: 2004
Flavan-3-ol (Flavanol) identification and quantitation by high performance liquid chromatography coupled with mass spectrometry (HPLC-MSn). Author(s): OLIVEIRA, J. B. DE; OLIVEIRA, C. G. R. de; PEREIRA, G. E. Flavan-3-ols are widely distributed in higher plants, such as grapes, located in the skins and seeds, being transferred to the wine during winemaking. They are responsible for specific sensory propert... ... Repository: BDPA Publication year: 2023
Determination of moxidectin in serum by liquid chromatography-tandem mass spectrometry and its application in pharmacokinetic study in lambs. Author(s): BAPTISTA, R. C.; FERNANDES, M. A. M.; GILAVERTE, S.; QUEIROZ, S. C. do N. de; ASSALIN, M. R.; FERRACINI, V. L.; MONTEIRO, A. L. G.; REYES, F. G. R. Abstract: The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced the parasite resistance in Brazilian farms. As a consequence, the farmers often increase the do... ... Repository: BDPA Publication year: 2017
