Cytotoxicity was significantly higher in leaf extracts when compared to extracts of other tissue types. Metabolic profiling indicated the predominance of non-protein amino acids, alkaloids and N-containing compounds, particularly in the leaf and stem extracts. Ultra Performance Liquic Chromatography (UPLC)-MS qTOF: UPLC-MS q-TOF is used for analyzing intact protein flavor interactions. It has an electrospray ionization and time of flight detector.

The flow from the UPLC column was split equally Ultraperformance liquid chromatography mass spectrometry (UPLC-MS), flow injection mass spectrometry (FIMS), and headspace gas chromatography (headspace-GC) combined with multivariate data analysis techniques were examined and compared in differentiating organically grown oregano from that grown conventionally. It is the first time that headspace-GC fingerprinting technology is reported in 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%, acetic acid 3% and Tenax ®) and analyzed by UPLC-MS/QTOF. 11:30-12:10 Title: Applications of UPLC-MS QTOF in structural elucidation of small molecules Peng Chen, Chemic Labs Inc., USA 12:10-12:15 Questionnaires Workshop 12:15-12:55 Title: HPLC method development and troubleshooting Marc Plante, Boston Analyticals, USA 12:55-13:00 Questionnaires Lunch Break 13:00-14:00 @ Dorothy Hall 14:00-14:40 Methanolic extracts were further analysed using UPLC/MS QToF for metabolic profiling.

• Running of analyses and identify metabolites and potential biomarkers through UPLC/MS: QTOF, Synapt and QExactive (Waters), Orbitrap (Thermo), TripleTOF (AB… • Work closely with external collaborators to design and develop novel assays for sample extraction efficiacy, rapid screening LC-MS and statistical analysis, leading to publications and manuscripts Natural health products (NHPs) are defined as natural extracts containing polychemical mixtures; they play a leading role in the discovery and development of drugs, for disease treatment. More than 50% of current cancer therapeutics are derived from natural sources. However, the efficacy of natural extracts in treating cancer has not been explored extensively.

Simultaneous Determination and Quantification of Triterpene Saponins from Camellia sinensis Seeds Using UPLC-PDA-QTOF-MS/MS. Hello, I am having a problem with pressure and retention time with Waters UPLC QTOF system. Retention times are about 1-1.5 min late. Pressure is at ~11000 psi (3000 psi higher than normal) and drops about 3000 psi every ~20 sec interval consistently.
