Flavanonol, numbering

El flavanonols (con dos "o"s aka 3-hydroxyflavanone o 2,3-dihydroflavonol) son una clase de flavonoide que usa la 3-hydroxy-2,3-dihydro-2-phenylchromen-4-one (IUPAC name) backbone.

Algunos ejemplos incluyen:

Metabolismo

  • Flavanona 3-dioxygenasa
  • Flavonol sintasa
  • Dihidroflavonol 4-reductasa

Glucósidos

Glycosides (chrysandroside A y chrysandroside B) se pueden encongtrar en las raíces de Gordonia chrysandra.[1]​ Xeractinol, a dihydroflavonol C-glucoside, puede ser aislada de las hojas de Paepalanthus argenteus var. argenteus.[2]

Dihydro-flavonol glycosides (astilbin, neoastilbin, isoastilbin, neoisoastilbin, (2R, 3R)-taxifolin-3'-O-beta-D-pyranoglucoside) han sido identificadas en los rizomas de Smilax glabra.[3]
