After hydrolysis into the fatty acid and sugar components and hydrophilic interaction chromatography–QTOFMS analysis, the extracellular lipids were found to consist of hydroxy fatty acids and sugar alcohols. Derivatization and chiral separation... T Cajka,LA Garay,IR Sitepu,... - 《Journal of Natur...
GC-QTOF-MS extracts were run in negative chemical ionization (NCI) for 21 targets (mainly pyrethroids) at sub-ng/L levels. For suspect screening, extracts were rerun in electron ionization (EI) mode with a retention time locked method using a GC-QTOF-MS pesticide library (containing exact ...
A GC-QTOF-MS methodology was optimized and validated, and five triterpenes were identified and quantified in all olive leaves samples analysed. ANOVA analyses revealed quantitative differences among sampling times and cultivars. Principal Component Analyses showed a good separation among triterpenes content...

3.8. LC-QTOF-MS and GC–MS profiling For further phytochemicals exploration, out of six samples under study, the phytochemically rich sample i.e., SA-03 was opted for LC-MS and GC–MS profiling. The GC–MS chromatogram of SA (i.e., SA-03) methanolic extract exhibited more than ten ...
Analysis of volatile and semivolatile flavour components in cigarettes by HS-SPME and GCxGC–QTOFMS Tobacco is known to content a highly complex mixture of flavour components, many of which are formed during the different curing processes of the leaves. T... J Regueiro,A Giri,Z Zelinkova,.....

2.8 LC-MS analysis LC-MS was performed using an ACQUITYTM UPLC-QTOF platform (Waters, Wexford, Ireland) with a Waters ACQUITY UPLC HSS T3 column (2.1 mm × 100 mm, 1.8 μm). The mobile phases consisted of 0.1% aqueous formic acid (v/v) (A) and acetonitrile (B), and were...
Comparative metabolism of cyclophosphamide and ifosfamide in the mouse using UPLC-ESI-QTOFMS-based metabolomics. Ifosfamide (IF) and cyclophosphamide (CP) are common chemotherapeutic agents. Interestingly, while the two drugs are isomers, only IF treatment is known to... L Fei,AD Patterson,CC H?
