Abstract:

Memecik olive oil variety which cultivated in six different locations were evaluated the effects of geographical locations on the chemical characterization of in the southwest of Turkey. The agricultural ecological map of each location was created using GIS. Olive oil samples were analyzed fatty acid, sterol and phenolic. Moreover, LC IMS QTOF spectrometer and Progenesis QI software were used to determine the geographical fingerprints of olive oil samples in different locations. Results showed that oil qualities of all locations differ significantly depending on olive growing area (p <0.05)

Abstract:

Ion mobility can add a dimension to LC-MS based shotgun proteomics which has the potential to boost proteome coverage, quantification accuracy and dynamic range. Required for this is suitable software that extracts the information contained in the four-dimensional (4D) data space spanned by m/z, retention time, ion mobility and signal intensity. Here we describe the ion mobility enhanced MaxQuant software, which utilizes the added data dimension. It offers an end to end computational workflow for the identification and quantification of peptides and proteins in LC-IMS-MS/MS shotgun proteomics

Abstract:

Dehydrodicatechins resulting from (epi)catechin oxidation have been investigated in different foods and natural products, but they still offer some analytical challenges. The purpose of this research is to develop a method using ultra-high performance liquid chromatography coupled with trapped ion mobility spectrometry and tandem mass spectrometry (UHPLC−ESI−TIMS−QTOF−MS/MS) to improve the characterization of dehydrodicatechins from model solutions (oxidation dimers of (+)-catechin and/or (−)-epicatechin). Approximately 30 dehydrodicatechins were detected in the model solutions, including dehy

Abstract:

Metabolomics-based approaches are still receiving growing attention with regard to food authenticity testing. Such studies require enormous sample numbers with negligible experimental or analytical variations to obtain statistically reliable results. In this context, an extraction protocol in line with optimized ionization parameters was developed in consideration of potential starch-derived matrix effects focusing on the polar lipids of potatoes. Therefore, well-known extractions (Bligh and Dyer, Folch, Matyash, and a n-hexane-based procedure) were compared in a non-targeted and a targeted ap

Abstract:

This review serves to highlight the role of chemometrics and biochemometrics in recent literature as well as including a perspective on the current state of the field, as well as the future needs and possible directions. Specifically examining the analytical methods and statistical tools that are available to chemists, current applications of QTOF-MS, Orbitrap-MS, LC with PDA/UV detectors, NMR, and IMS coupled MS are detailed. Of specific interest, these techniques can be applied to botanical dietary supplement quality, efficacy, and safety. Application in natural products drug discovery, indu

Abstract:

Abstract Background The production of hospital-compounded medicines with a longer shelf life raises questions about drug-packaging interactions, especially desorption events involving extractables and leachables (E/L). A meta-synthesis of the literature was performed to describe which mass spectrometer is suitable for identifying and quantifying E/L. Methods A meta-synthesis of studies focused on the identification or quantification of E/L published between January 1997 and December 2017 was performed. Inclusion criteria were E/L studies dealing with pharmaceutical products, in which mass spec

Abstract:

Abstract Background A pathognomonic feature of multiple myeloma is the presence abnormal monoclonal immunoglobulin, of which immunoglobulin G (IgG) paraprotein is the most common. All subclasses of Igs are post-translationally modified by the addition of N-glycans. The added N-glycosylation plays a key role in modulating the structure and function of the antibody. It has been recently demonstrated that high resolution mass spectrometry can facilitate the detection of myeloma associated monoclonal immunoglobulin. Herein, a simple method for the enrichment of monoclonal immunoglobulin from total
