Eriodictyol is a bitter-masking flavanone, a flavonoid extracted from Yerba Santa (Eriodictyon californicum), a plant native to North America. Eriodictyol is one of the 4 flavanones identified in this plant by the Symrise Corporation as having taste-modifying properties, the other three being: homoeriodictyol, its sodium salt and sterubin. Eriodictyol was also found in the twigs of Millettia duchesnei, in Eupatorium arnottianum and one of its glycoside in rose hips (Rosa canina).
