Quercetin is a flavonoid widely distributed in nature. [2] The name has been used since 1857, and is derived from quercetum (oak forest), after the oak genus Quercus. [4] [5] It is a naturally occurring polar auxin transport inhibitor. [6] Quercetin is one of the most abundant dietary flavonoids, [2] [3] with an average daily consumption of 25 ...
Lamaison and Carnet have designed a test for the determination of the total flavonoid content of a sample (AlCI 3 method). After proper mixing of the sample and the reagent, the mixture is incubated for ten minutes at ambient temperature and the absorbance of the solution is read at 440 nm. Flavonoid content is expressed in mg/g of quercetin ...

A good source of protein provides a dog with a balanced and complete profile of amino acids, and is essential for growth, muscle maintenance, and various cellular functions. [38] In a plant-based dog food, the protein composition can be sourced from a variety of ingredients, such grains, rice, corn, wheat, and/or barley.
Rutin (rutoside, quercetin-3-O-rutinoside or sophorin) is the glycoside combining the flavonol quercetin and the disaccharide rutinose (α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranose). It is a flavonoid glycoside found in a wide variety of plants, including citrus .
Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
Isorhamnetin is an O-methylated flavon-ol from the class of flavonoids.A common food source of this 3'-methoxylated derivative of quercetin and its glucoside conjugates are pungent yellow or red onions, in which it is a minor pigment, quercetin-3,4'-diglucoside and quercetin-4'-glucoside and the aglycone quercetin being the major pigments.
