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.^[2]

Recent research has demonstrated some neuroprotective properties of Sterubin in vitro, but more research is needed before it can be considered a true drug candidate.^[3][4][5]
