Eriodictyol

Eriodictyol is a bitter-masking flavanone, a flavonoid extracted from yerba santa (Eriodictyon californicum), a plant native to North America.^[1] Eriodictyol is one of the four flavanones identified in this plant as having taste-modifying properties, the other three being homoeriodictyol, its sodium salt, and sterubin.^[2]

Eriodictyol has garnered scientific attention for its strong antioxidant, anti-inflammatory, and neuroprotective properties. Structurally similar to other flavonoids, such as hesperidin and naringenin, eriodictyol scavenges free radicals and regulates inflammatory responses.

Eriodictyol was also found in the twigs of Millettia duchesnei,^[3] in Eupatorium arnottianum,^[4] and its glycosides (eriocitrin) in lemons and rose hips (Rosa canina).^[5]

Eriodictyol belongs to the flavanone subclass of flavonoids and has a chemical structure defined by the molecular formula C₁₅H₁₂O₆, with a molecular weight of 288.25 g/mol.^[6]
