Compound Monograph
Quercetagetin
Quercetagetin is a flavonol pigment related to quercetin, found in marigold and tarragon species.
Classification
Quercetagetin is a flavonoid (flavonol), part of the phenolics class. Antioxidant compounds built around one or more phenol rings — the flavonoids, tannins, phenolic acids, coumarins, and pigments behind much of a plant's protective chemistry.
Where Does It Come From? (2)
Quercetagetin is a naturally occurring flavonoid (flavonol), found in Mexican tarragon and Marigold. It is well tolerated orally (low toxicity).
Research & Evidence
Quercetagetin is a flavonol, essentially quercetin bearing an additional hydroxyl group, and it occurs as a yellow pigment in marigold (Tagetes) flowers and related plants. Like other flavonols it is studied chiefly for antioxidant and enzyme-modulating activity in laboratory settings. Its specific effects in humans are not well established.
Toxicity & Safety
As a plant flavonoid consumed in small dietary amounts, quercetagetin is regarded as low in toxicity. A dedicated human safety profile has not been characterised.
