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.

Keywords: Dendrobium officinale; anthocyanin; UPLC-MS-QTOF; anthocyanidin synthase 1. Introduction Dendrobium officinale (Chinese name: Tie-pi-shi-hu) is an edible perennial orchid plant that has commonly been employed as a functional food in China and other Asian countries for thousands of years [1]. 2010-10-01 · 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. 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.

FREC SERVICES. The Flavor Research and Education Center (FREC) works to understand drivers of flavor perception and, ultimately, food choice. We have built a holistic analytical platform that combines our extensive expertise with modern and advanced instrumentation to investigate and address unique and challenging aspects of flavor discovery. UPLC‐MS‐QTOF has been used to identify the compounds of high molecular weight present in the HCl‐SPE fraction separated from HOP from the conventional pyrolysis experiment, N2. The compounds identified by UPLC‐MS‐QTOF are pentylimidazole, hexylimidazole, trimethoxybenzene, heptylimidazole, octylimidazole, nonylimidazole, n ‐hexyl‐5‐oxododecamide, octocrylene, dietildodecamide Fatty acids and sterols were determined by GC‐MS, MDA by colorimetric assay, vitamin A by HPLC. 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.
