Flavonol

The majority of flavonol glycosides (including dihydroflavonols) are present as O-glycosides and not C-glycosides (see Glycosylation Patterns below). Most glycosides are 3-, 7-, 3'-, 4'-glycosides and their combinations. Only flavonols and flavones contain rare glycosidic sugars such as alloside (allose), mannoside (mannose), galacturonic acid (galacturonide), and apioside (this is found in isoflavone too).
Also, 2 flavonols (FL5FF8NS0002 FL5FF8NSH001) are exceptionally found from a fungus Aspergillus candidus.

The 5th and 6th digits of our flavonoid ID indicates the hydroxylation patterns of A-ring and B-ring (See the upper-right figure. The leftmost ring is A, rightmost is B), respectively. The following chart is spanned by these 2 digits. R indicates H or CH₃, and R' indicates H or R. Numbers are IUPAC positions. The value in each cell (such as GS: glycosilation only) corresponds to the 7th and 8th digits, which is explained at the bottom of this page.
