A simple and effective preparation of quercetin pentamethyl ether from quercetin [PDF]
Beilstein Journal of Organic Chemistry, 2018 Among the five hydroxy (OH) groups of quercetin (3,5,7,3',4'-pentahydroxyflavone), the OH group at 5 position is the most resistant to methylation due to its strong intramolecular hydrogen bonding with the carbonyl group at 4 position. Thus, it is generally difficult to synthesize the pentamethyl ether efficiently by conventional methylation.

Journal of the American Oil Chemists' Society, EarlyView.Annatto‐derived bixin and norbixin were characterized and evaluated as natural antioxidants for soybean biodiesel. Their antioxidant performance and effects on oxidative stability were assessed using DPPH, Rancimat, and PetroOXY methods. ABSTRACT The increasing use of eco‐friendly fuels is increasing the production of biodiesel but soybean biodiesel is

Interaction of quercetin with DNA
Bioscience Reports, 1986 I n vitro experiments to study interaction of the mutagenic flavonoid quercetin with DNA are described. Calf thymus DNA treated with quercetin for various time periods was subjected to S1 nuclease hydrolysis. Thermal melting profles of treated DNA were also determined using St nuclease.
