Lipid profiling of human plasma from peritoneal dialysis patients using an improved 2D (NP/RP) LC-QToF MS method.
An improved online two-dimensional liquid chromatography-quadrupole time-of-flight mass spectrometry (2D LC-QToF MS) system was developed for the lipid profiling of human plasma, in which different lipid classes were separated by the first dimensional normal-phase (NP) LC and different lipid molecular species were separated by the second dimensional reversed-phase (RP) LC. This 2D LC-QToF MS sy...
متن کاملQuantitation of cyclic dinucleotides by reversed-phase LC-MS/MS
Cyclic dinucleotides such as bis-(3',5')-cyclic dimeric adenosine monophosphate (c-di-AMP) and bis-(3',5')-cyclic dimeric guanosine monophosphate (c-di-GMP) represent important second messengers in bacteria. Although their synthesis has not been described in plants so far, they may be involved in the regulation of bacterial phytopathogen-plant interactions as well as rhizobium plant symbiosis. ...
متن کاملLC-ESI-MS/MS Alkaloidal Profiling and Biological Investigation of Cleistocactus winteri Stems
Cleistocactus winteri is a succulent plant of the Cactaceae family, commonly known as the golden rat tail. Many members of the Cactaceae family are the focus of chemical and biological studies as they contain bioactive compounds, well known for their health-related properties. We aimed to investigate Cleistocactus winteri stems both phytochemically and biologicallyfor the firs...

متن کاملSelective separation, detection of zotepine and mass spectral characterization of degradants by LC–MS/MS/QTOF
A simple, precise, accurate stability-indicating gradient reversed-phase high-performance liquid chromatographic (RP-HPLC) method was developed for the quantitative determination of zotepine (ZTP) in bulk and pharmaceutical dosage forms in the presence of its degradation products (DPs). The method was developed using Phenomenex C18 column (250 mm×4.6 mm i.d., 5 µm) with a mobile phase containin...
