Eriodictyol Explained

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 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]
