UPLC-MS/QTOF ABSTRACT Migration of non volatile compounds from twenty six PP ﬁlms used as food contact materials has been studied in four simulants (ethanol 95% and 10%,

Cyperus has been commonly used as a multi-use medicinal plant in folk medicine worldwide. The objectives of our study were to determine the different metabolites in the Cyperus conglomeratus Rottb. methanol extract, and to assess its in vivo gastroprotective effect in ethanol-induced gastric ulcer model in rats. An ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC–qTOF-MS/MS) method was developed and validated for the simultaneous determination of glycyrrhizin and glycyrrhetic acid. The Magnolia denudata flower is used to prepare tea and is often fermented to improve its flavor. Herein, fresh, aged, and browned M. denudata flower extracts were characterized using ultra performance liquid chromatography coupled with a hybrid quadrupole orthogonal time-of-flight mass spectrometer (UPLC-Q-TOF/MS/MS).

Vitamin A ester profiles were determined by UPLC‐MS (QTOF). The ratio of DHA/EPA for MD products was 1.3–1.7 with one exception, while the fermented product (0.5), and crude samples (2.2–3.3) were different. Europe PMC is an archive of life sciences journal literature. By coupling a single UPLC separation to two different types of mass spectrometer an unbiased comparison of the metabolite profiles produced by each instrument for a set of rat urine samples was obtained. Identification and quantification of non-volatile compounds was carried out by UPLC-MS-QTOF. Most of migrants were oligomers such as cyclic polyesters and caprolactam oligomers. Overall migration and specific migration of adipic acid-diethylene glycol and phthalic acid-diethylene glycol were monitored over time and analysed by UPLC-MS-TQ.

In this work the “omics” interface was validated with a set of 37 wines; 42 biomarkers were extracted from GC-MS and 152 from UPLC-MS-QTOF. The development of tools such as network reconstruction provided considerable amount of information that contributed to the understanding of the kinetic contexts of the molecules (through ageing time).
