What is "sterubin"

Sterubin (7-methoxy-3',4',5-trihydroxyflavanone) is a bitter-masking flavanone extracted from Yerba Santa ( Eriodictyon californicum) a plant growing in America.

Sterubin is one of the four flavanones identified by Symrise in this plant which elicit taste-modifying properties. The others are homoeriodictyol, its sodium salt, and eriodictyol.
