Wang R, Xu Z, Yang X. Study the key biogenic amines in luncheon meat by capillary electrophoresis with indirect UV detection. J Sep Sci 2022; 45:4107-4115. [PMID: 36086796 DOI: 10.1002/jssc.202200474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 09/01/2022] [Accepted: 09/06/2022] [Indexed: 11/11/2022]
Abstract
In this work, a simple, accurate and rapid capillary electrophoresis with indirect ultraviolet detection method was developed to simultaneous separate 10 biogenic amines. It was found that β-cyclodextrin and ethylene diamine tetraacetic acid facilitated the separation of tryptamine and tyramine, spermidine and spermine, respectively. The optimized background electrolytes were consisted of 20.0 mmol/L imidazole, 8.0 mmol/L β-cyclodextrin, 0.5 mmol/L ethylene diamine tetraacetic acid and 6.0% methanol (at pH 4.50 adjusted with acetic acid). The total analysis time of this method was less than 11 min with limits of detection in the range of 0.14-1.98 mg/L. The interday relative standard deviation of migration time and peak area were less than 1.36% and 4.44% (n = 6), respectively. To verify the applicability, this method was carried out to analyze biogenic amines in commercial luncheon meat samples. Due to the complex composition of luncheon meat, the real samples were rinsed with deionized water to reduce the influence of matrices. It was found that both storage temperature and protein content of the luncheon meat samples affected the biogenic amines content during storage. The results of this study are instructive for the storage of high-protein meat products. This article is protected by copyright. All rights reserved.

Recent Applications of Capillary Electrophoresis in the Determination of Active Compounds in Medicinal Plants and Pharmaceutical Formulations. Molecules 2021; 26:4141. [PMID: 34299418 PMCID: PMC8307982 DOI: 10.3390/molecules26144141] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 06/29/2021] [Accepted: 07/05/2021] [Indexed: 11/28/2022] Open
Abstract
The present review summarizes scientific reports from between 2010 and 2019 on the use of capillary electrophoresis to quantify active constituents (i.e., phenolic compounds, coumarins, protoberberines, curcuminoids, iridoid glycosides, alkaloids, triterpene acids) in medicinal plants and herbal formulations. The present literature review is founded on PRISMA guidelines and selection criteria were formulated on the basis of PICOS (Population, Intervention, Comparison, Outcome, Study type). The scrutiny reveals capillary electrophoresis with ultraviolet detection as the most frequently used capillary electromigration technique for the selective separation and quantification of bioactive compounds. For the purpose of improvement of resolution and sensitivity, other detection methods are used (including mass spectrometry), modifiers to the background electrolyte are introduced and different extraction as well as pre-concentration techniques are employed. In conclusion, capillary electrophoresis is a powerful tool and for given applications it is comparable to high performance liquid chromatography. Short time of execution, high efficiency, versatility in separation modes and low consumption of solvents and sample make capillary electrophoresis an attractive and eco-friendly alternative to more expensive methods for the quality control of drugs or raw plant material without any relevant decrease in sensitivity.
