Analysis of flavonoids in citrus fruits by capillary zone electrophoresis coupled with quadrupole time-of-flight mass spectrometry using chemometrics

Fluorescence enhancement of flavonoids and its application in ingredient determination for some traditional Chinese medicines by CE-LIF

“…34 Using CE-DAD (diode array detection), 28 kaempferol and quercetin could be found in chamomile. Using CE-MS, 35 kaempferol could be found in citrus fruits. Using LC-DAD and LC-MS, 36 quercetin could be found in cacumen biotae.…”

“…18 Besides AD, UV and MS have been frequently applied for detecting avonoids. [19][20][21] Compared with the above detection modes, LIF detection belongs to uorescence detection and it is a sample non-contact detection method that can greatly reduce the interference during detection. Furthermore, this detection mode is sensitive and easy to operate.…”

Capillary Electrophoresis: A Three-Year Literature Review

“…CE is a cost-effective technique that offers excellent resolution and sensitivity, making it an attractive analytical platform for complex food matrices. In the past couple of years, CE-based techniques have been widely applied for the analysis and monitoring of nutritional ingredients in a variety of food products, e.g., amino acids in beers, flavonoids in citrus fruits, monosaccharides in ginkgo bilobas, and starch in rice . They have also been used to determine essential components in milk, such as lactose, lactulose, unsaturated fatty acids, and protein compositions, demonstrating their potential as a routine analytical tool for the dairy industry. − …”

Capillary electromigration methods for food analysis and Foodomics: Advances and applications in the period March 2021 to March 2023

“…For instance, the use of MS or laser‐induced fluorescence (LIF) detection methods can eventually be enough to determine minor components in food and food‐related samples, depending on the nature of the target components. This is illustrated by the development of a new method for the determination of flavonoids in citrus fruits combining a CZE separation together with a quadrupole time‐of‐flight (QTOF)–MS detector [46]. Quantitative analyses allowed grouping different citrus samples according to their typical composition in eight target flavonoids.…”
