Flavanonol

The flavanonols (with two "o"s aka 3-hydroxyflavanone or 2,3-dihydroflavonol) are a class of flavonoids that use the 3-hydroxy-2,3-dihydro-2-phenylchromen-4-one (IUPAC name) backbone.

Some examples include:

Metabolism

Glycosides

Glycosides (chrysandroside A and chrysandroside B) can be found in the roots of Gordonia chrysandra[1]. Xeractinol, a dihydroflavonol C-glucoside can be isolated from the leaves of Paepalanthus argenteus var. argenteus[2].

Dihydro-flavonol glycosides (astilbin, neoastilbin, isoastilbin, neoisoastilbin, (2R, 3R)-taxifolin-3'-O-beta-D-pyranoglucoside) have been identified in the rhizome of Smilax glabra[3].
