“…The main interfering compounds in grape wine samples are anthocyanidin and phenolic compounds. − To evaluate satisfactory cleanup following SPE pretreatment, three common types of SPE, including MCX SPE (Waters, 60 mg/3 mL), HLB SPE (Waters, 60 mg/3 mL), and ENVI C 18 (Superclean, 60 mg/3 mL), were tested to investigate their influences on recovery. The six target analytes yielded recoveries ranging between 83.5 and 94.1% when using HLB SPE and recoveries ranging between 65.1 and 74.8% when MCX and ENVI C 18 SPE were used.…”

A gas chromatography-tandem mass spectrometry (GC-MS/MS) method was developed for the first simultaneous identification and quantification of six pyrazole fungicides (furametpyr, rabenzazole, fluxapyroxad, penflufen, bixafen, and isopyrazam) in grape wine samples. The grape wine samples were first diluted with water, then purified by solid-phase extraction, and finally examined by GC-MS/MS in multiple reaction monitoring (MRM) mode. Matrix-matched calibration curves were used to correct the matrix effects. The limits of quantification (LOQs), calculated as 10 times the standard deviation, were 0.2-0.8 μg kg(-1) for the six pyrazole fungicides. The average recoveries were in the range of 74.3-94.5%, with relative standard deviations (RSDs) below 5.8%, measured at three concentration levels. The proposed method is suitable for the simultaneous determination of six pyrazole fungicides in grape wine samples.

“…When the LIT MS was scanning, the entrance RF-only section of the mass spectrometer was used as the accumulating ion trap, which could increase the duty cycle and increase the sensitivity by 20 times (Hager and Blanc, 2010). Sun et al (2015) used the enhanced product ion mode of the LIT on the hydrophilic interaction liquid chromatography (HILIC) Q-Trap MS to identify and quantify four anthocyanins in red grape wine.…”

Mass spectrometry (MS) is one of the most widely used analytical techniques in many fields. Recent developments in chemical and biological researches have drawn much attention to the measurement of substances with low abundances in samples. Continuous efforts have been made consequently to further improve the sensitivity of MS. Modifications on the mass analyzers of mass spectrometers offer a direct, universal and practical way to obtain higher sensitivity. This review provides a comprehensive overview of the latest developments in mass analyzers for the improvement of mass spectrometers’ sensitivity, including quadrupole, ion trap, time-of-flight (TOF) and Fourier transform ion cyclotron (FT-ICR), as well as different combinations of these mass analyzers. The advantages and limitations of different mass analyzers and their combinations are compared and discussed. This review provides guidance to the selection of suitable mass spectrometers in chemical and biological analytical applications. It is also beneficial to the development of novel mass spectrometers.

Strategies in the Analysis of Plant Flavonoids: An Update

Flavonoids are one of the largest groups of plant secondary metabolites. They comprise several thousand compounds that share a phenylchromane skeleton and can be classified into different classes, namely flavones, flavonols, flavanones, flavanols, anthocyanins, dihydroflavonols, isoflavones, and chalcones. Flavonoids occur in their natural sources as aglycones or glycosylated forms and as monomers or constituting polymerized structures and can be found both as free and matrix‐bound compounds. This structural diversity affects their physicochemical behavior, and different flavonoid classes and compounds may have different requisites for their extraction and analysis, so that there is not a unique analytical strategy that applies in all situations. In this article, the main methodological approaches to the analysis of flavonoids in plant materials are revised. Particular attention is paid to more recent extraction techniques and high‐performance liquid chromatography (LC)‐based methodologies coupled to different detection systems, and especially liquid chromatography coupled to mass spectrometry (LC‐MS) that currently dominates the field of flavonoid analysis.
