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]
