Umbelliferone
Umbelliferone is a hydroxycoumarin and a common plant secondary metabolite known for its blue fluorescence.
Classification
Umbelliferone is a coumarin (hydroxycoumarin), 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? (5)
Umbelliferone is a naturally occurring coumarin (hydroxycoumarin), found in Chamomile, Meadowsweet, Carrot and 2 other sources. It is well tolerated orally (low toxicity).
Research & Evidence
Umbelliferone (7-hydroxycoumarin) is a widely occurring coumarin found across many plant families, especially the carrot family (Apiaceae). It is well known for its strong blue fluorescence and absorption of ultraviolet light, properties that have led to its use in sunscreens and as a fluorescence standard. As a dietary phytochemical it has been studied for antioxidant and other biological activities, though most of this work is preclinical.
Toxicity & Safety
Umbelliferone occurs naturally in a number of common foods and herbs and is generally considered to have low toxicity at the levels typically encountered. Detailed safety data for concentrated use are limited.
