Flavanonol
![](http://upload.wikimedia.org/wikipedia/commons/thumb/8/86/Flavanonol_num.svg/200px-Flavanonol_num.svg.png)
The flavanonols (with two "o"s a.k.a. 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:
- Taxifolin (or Dihydroquercetin)
- Aromadedrin (or Dihydrokaempferol)
- Engeletin (or Dihydrokaempferol-3-rhamnoside)
Metabolism
- Flavanone 3-dioxygenase
- Flavonol synthase
- Dihydroflavonol 4-reductase
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-β-D-pyranoglucoside) have been identified in the rhizome of Smilax glabra.[3]
