Rapid Determination of Parabens in Water Samples by Ultra-high Performance Liquid Chromatography Coupled to Time of Flight Mass Spectrometry
(Japan Soc Analytical Chemistry, 2020)
An analytical methodology has been developed and validated for the purpose of identifying and quantifying four parabens (methylparaben, ethylparaben, propylparaben and n-butylparaben) in water samples. The combination of ...
Estudo químico e biológico dos extratos hexânico e clorofórmico de folhas de Cheiloclinium cognatum (Miers) A.C.Sm. (Celastraceae) e avaliação do perfil de fragmentação de seus triterpenos friedelânicos por APCI-IT-TOF
(Universidade Federal de Minas GeraisUFMG, 2016-02-26)
Phytochemical study of hexane and chloroform leaf extracts fromCheiloclinium cognatum resulted in the isolation of sixteen constituents. The isolation yielded three fatty compounds mixture of long chain hydrocarbons, ...
Amazonian Vegetable Oils and Fats: Fast Typification and Quality Control via Triacylglycerol (TAG) Profiles from Dry Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) Mass Spectrometry Fingerprinting
(AMER CHEMICAL SOC, 2009)
Amazonian oils and fats display unique triacylglycerol (TAG) profiles and, because of their economic importance as renewable raw materials and use by the cosmetic and food industries, are often subject to adulteration and ...

Identification of Corynebacterium spp. isolated from bovine intramammary infections by matrix-assisted laser desorption ionization-time of flight mass spectrometry
(Elsevier B.V., 2014-09-17)
Corynebacterium species (spp.) are among the most frequently isolated pathogens associated with subclinical mastitis in dairy cows. However, simple, fast, and reliable methods for the identification of species of the genus ...
Distinguishing two species of Cavernicola (Hemiptera, Reduviidae, Triatominae) with matrix-assisted laser desorption ionization time-of-flight mass spectrometry
(2019-10-01)
The blood-sucking insects of the subfamily Triatominae are vectors of Chagas disease, the most impairing protozoan parasitic infection in Latin America. Among the five tribes known in the subfamily, one of the least studied ...
