The sonochemical effects of ultrasound (US) treatment on 14 flavonoids representing the main flavonoids in citrus fruit were investigated in a standard mixture by stability evaluation of a model system. Degradation products were further tentatively identified by Fourier transform infrared spectroscopy and high-performance liquid chromatography–ultraviolet detection–electrospray ionization tandem mass spectrometry. Thirteen flavonoids (i.e., eriocitrin, narirutin, neohesperidin, quercitrin… 
Flavonoids from Epimedium pubescens: extraction and mechanism, antioxidant capacity and effects on CAT and GSH-Px of Drosophila melanogaster
TLDR
Flavonoids of E. pubescens showed great potential for becoming a natural antioxidant because of their antiradical ability and effects on CAT and GSH-Px of the model organism.

Effect of thermal processing on the flavonols rutin and quercetin.
TLDR
The current research involves the study of the thermal treatment of quercetin and rutin in an aqueous model system (cooking), which showed strong degradation of the model substances took place under weak basic and oxidative conditions.

Effect of heat treatment on the phenolic compounds and antioxidant capacity of citrus peel extract.
TLDR
The results showed that after heat treatment, the free fraction of phenolic acids increased, whereas ester, glycoside, and ester-bound fractions decreased and the content of total FGs declined, suggesting that a proper and reasonable heat treatment could be used to enhance the antioxidant capacity of citrus peel.
Comparative analysis of quercetin oxidation by electrochemical, enzymatic, autoxidation, and free radical generation techniques: a mechanistic study.
TLDR
This work demonstrates that the presence of water and/or nucleophiles as well as different catalysts (tyrosinase, AIBN, or air oxygen in solution) may have very important implications for the formation of quinone with subsequent oxidative cleavage or polymerization.
The UVA and aqueous stability of flavonoids is dependent on B-ring substitution.
TLDR
It is determined that flavonol stability decreases with increasing B-ring substitution, suggesting that future investigation of potential photoprotective flavonols will need to be cognizant of this trend.
