TLDR
Special attention will be devoted to the use of tandem-mass spectrometric (MS/MS) techniques for the characterization of several important sub-classes of flavonoids, and to the potential of combined diode-array UV (DAD UV), tandem-MS and nuclear magnetic resonance (NMR) detection for unambiguous identification.About:

Flavonoid composition of Citrus juices.
TL;DR: Analytical techniques for the characterization of juices from different Citrus fruits regarding their flavonoid content (even if present in only trace amounts), concentrating on the most widely used methods (LC-MS and LC-MS-MS).
Journal ArticleDOI
Anti-inflammatory effects of flavonoids.
TL;DR: The present review focused in flavonoids, the most abundant polyphenols in the diet, to give an overview of the most recent scientific knowledge about their impact on different inflammatory diseases.

Microwave-Assisted Extraction of Flavonoids: A Review
Winny Routray,V. Orsat +1 more
TL;DR: In this paper, the potential application of microwave extraction for flavonoids and the advantage of microwave-assisted process over the other extraction processes generally employed for extraction are reviewed and compared. But, microwave extraction is one of the most advanced extraction methods, which has the potential of playing a major role in flavonoid extraction and analytical quantification.

Flavonoids as Antioxidants
TL;DR: This review presents the current knowledge on structural aspects and in vitro antioxidant capacity of most common flavonoids as well as in vivo antioxidant activity and effects on endogenous antioxidants.
Journal ArticleDOI
Antioxidant properties of phenolic compounds
TL;DR: It is now possible to establish the antioxidant activities of plant-derived flavonoids in the aqueous and lipophilic phases, and to assess the extent to which the total antioxidant potentials of wine and tea can be accounted for by the activities of individual polyphenols.
Journal ArticleDOI
A systematic nomenclature for carbohydrate fragmentations in FAB-MS/MS spectra of glycoconjugates
TL;DR: A systematic nomenclature has been developed primarily for FAB-MS, but can be used as well for other ionization techniques and is applicable to spectra recorded in either the positive or negative ion mode during both MS and MS/MS experiments.
Journal ArticleDOI
The biochemistry and medical significance of the flavonoids.
TL;DR: Flavonoids are plant pigments that are synthesised from phenylalanine, generally display marvelous colors known from flower petals, mostly emit brilliant fluorescence when they are excited by UV light, and are ubiquitous to green plant cells.
