The flavanonols are a class of flavonoids that use the 3-hydroxy-2,3-dihydro-2-phenylchromen-4-one backbone.
Some examples include:
Glycosides can be found in the roots of Gordonia chrysandra. Xeractinol, a dihydroflavonol C-glucoside, can be isolated from the leaves of Paepalanthus argenteus var. argenteus.
Dihydro-flavonol glycosides have been identified in the rhizome of Smilax glabra.
